Facial expressions can reflect people’s inner emotions to a certain extent, and studying facial expressions can help psychologists capture expression information in time and understand patients’ psychological changes quickly. In this paper, we establish a multi-channel convolutional neural network face expression recognition model based on the fusion of the attention mechanism. With the help of the attention mechanism and multi-channel convolutional neural network, we input expression images and perform average pooling and maximum pooling, output the features with high recognition after pooling, and identify the features with high recognition in expression images throughout the process. And with the help of multi-scale feature fusion, we improve the detection of subtle changes, such as the corners of the mouth and the eyes of the expression image target. The loss function is used to calculate the loss rate of facial expression images, which leads to the correct rate of facial expression recognition by a multi-channel convolutional neural network based on the fusion of attention mechanisms. It is demonstrated that the highest recognition correct rate of the multi-channel convolutional neural network faces expression recognition model with attention mechanism fusion is 93.56% on the FER2013 dataset, which is higher than that of the MHBP model by 23.2%. The highest correct recognition rate on the RAF-DB dataset is 91.34%, which is higher than the SR-VGG19 model by 19.39%. This shows that the multi-channel convolutional neural network face expression recognition based on the fusion of attention mechanisms improves the correct rate of facial expression recognition, which is beneficial to the research and development of psychology.

Comparison with other algorithms revealed that the average PSNR of the MLP algorithm improved by 4.43% over the Ma algorithm, 7.88% over the Vanmail algorithm, 10.30% over the FMMR algorithm, 11.19% over the PMF algorithm, and 11.19% over the PMF algorithm. For PCC, the MLP algorithm improves by 20.14%, 17.46%, 2.31%, 11.24%, and 15.36% over the other algorithms in that order. For SSMI, the MLP algorithm improved by 16.99%, 8.96%, 17.17%, 14.41%, and 4.85% over the other algorithms, in that order. For HDR-VDR-2, the MLP algorithm improved by 3.02%, 2.79%, 6.84%, 4.90%, and 6.55% over the other algorithms, in that order. The results show that the MLP algorithm can avoid image artifacts while retaining more details. The MLP-based adaptive fusion method is a step further in the theoretical study of multi-exposure image fusion, which is of great significance for subsequent research and practical application by related technology vendors.
With the improvement of information technology, all industries have developed rapidly. However, the education industry is lagging behind in the process of informationization. Most still follow the educational paradigm of the past, where teachers rely on personal experience to make judgments and teaching decisions for students, just like a blind man feeling like an elephant. In this paper, we design a teaching quality monitoring and evaluation strategy according to the K-modes algorithm in big data technology, which is a dynamic data collection and intelligent analysis based on the learning process and learning effectiveness, ensuring data authenticity and also realizing multi-dimensional data collection and multi-angle evaluation and analysis, and finally comparing each index of three different algorithms. It is verified that the minimum error sum of squares of the optimized K-modes algorithm is 711, and the correct rate is 0.97, while the values of this metric for the other two algorithms are 1587 and 986, and the correct rates are 0.91 and 0.92, respectively. Therefore, the designed mechanism is a system with a superior evaluation effect and a feasible prediction model for faculty development in local vocational colleges.
English education for college students is a major instructional programme with significant developmental importance; yet, its conversations are also crucial. Reflexivity in conversational repair refers to the tendency of speakers to go back to the beginning of the repairing component rather than to implement the repair directly after the wrong word. In order to help listeners solve the connection problem, speakers use different back-referencing strategies. In this study, we used a quantitative and qualitative approach to explore the patterns and strategies of finger-back repair in Chinese college students’ English conversations and to compare their similarities and differences with native speakers in the use of finger-back onset words. The study found that the proportion of self-repetition was the highest among college students, reaching about 75%, and the proportion of reorganisation and insertion strategies was very small, about 23%, which reflected the characteristics of college students’ ability in linguistic information processing and online processing; moreover, there were significant differences between them and native speakers in the use of reflexive priming words. This paper borrows from the attention theory of cognitive psychology to explain the results and to point out the implications of this study for the teaching of spoken English in college.

The trajectory tracking of badminton players’ arm shots can be used effectively to enhance the player’s shot quality. To track the image trajectory of the batting arm, it is necessary to calculate the body posture ratio and tightness of the target area of the batting arm, to filter the background interference of the image segment of the batting and to complete the efficient tracking of the trajectory of the arm batting image. The traditional method combines the adaptive threshold segmentation method to extract the hitting arm target from the background, but ignores filtering out the background interference of the hitting image fragment. This paper proposes a trajectory tracking method based on the morphological operator of the batter image of the arm stroke. The method consists of (1) differentially calculating the image sequence of the hitting arm during two consecutive shots, (2) estimating the Gaussian model parameters of the differential image of the hitting arm during the hitting process, (3) extracting the outline of the moving target of the hitting arm during the hitting process and then calculating the body posture ratio of the hitting target area and compactness, (4) filtering the background interference of the shot image fragment, (6) constructing a global matching approximation function of the moving target and (7) finally determining the motion trajectory of the badminton arm of the batter. Simulation results show that the proposed method can effectively track the target of the hitting arm during the hitting process and generate a continuous trajectory of the hitting arm.

Meantime, the extent of the tolerance effect of the random parameters on the waterproof performance is explored.
For the third-party cross-border e-commerce sharing platform, due to the lack of management and operation mechanism, the current sharing platform has relatively high fees, insufficient publicity, and consumption methods are not conducive to Chinese consumers. There are obvious problems such as insufficient personnel training. In this article, we use the CGA-LSO-BP network to solve the problems of various systems disjoint, complicated department settings, confusing distribution of powers and responsibilities in the training base, as well as unclear division of team functions, technology mismatch, and the training base itself. The scale, social reputation and other factors lead to the difficulty of reducing financing channels and other related operation and management issues to study and analyze. The results show that the minimum error can reach 0.5% for CGA-LSO-BP, which is much smaller than the traditional algorithm. It is proved that the algorithm can help the BP neural network to jump out of the local optimal value to a certain extent, and play an active role in the regression task. In addition, the improved CGA-LSO-BP neural network based on this can provide a good reference for various problems in cross-border e-commerce, such as disjointed systems, complicated department settings, and chaotic distribution of rights and responsibilities, and propose optimal solutions.
The paper establishes a related differential equation model about changes in financial interest rates. It uses information related to liquidity to feedback the law and stability of differential equations in interest rate changes. The article applies stochastic processes and partial differential equations to complex financial networks to confirm node yields in financial market networks. It confirms the existence of interest rate stickiness in Chinese financial markets. The advantage of this interest rate model is that when the external economic environment changes, the state of interest rates will also change accordingly.
In order to enhance national competitiveness while ensuring the rational operation of world trade activities, the highly internationalized development of cobalt trade is promoted. This paper analyzes the current situation of world cobalt trade through the collection and collation of trade network data. That is, each node on the network represents an activity subject, and the relationship between nodes and nodes exists in terms of commodity demand and supply, reflecting the network Spatio-temporal divergence characteristics of global commodity trade. By measuring the topological network indicators such as density, point degree, intermediary centrality, and proximity to the center, the influence of a country in the trade network and whether it occupies the central position can be more clearly defined, effectively capturing the strength of the relationship between the nodes in the world trade network and facilitating the understanding of the evolution mechanism of the world trade network, and using the QAP regression model to calculate the relationship and trade volume between two countries that affect the trade connection. The results of the study show that China’s cobalt production in 2021 is 2,105 tons, down 8.5% year-on-year. With the passage of time, the overall scale of the international trade network of bauxite is growing, the number of countries involved in the trade is increasing, the trade volume is growing, and the trade relationship between countries is gradually increasing, which reflects the good development trend of global bauxite trade.
Diamond, a wide bandgap semiconductor material, has excellent physicochemical properties. It has great potential for application in high temperature, high frequency, high power electronic devices and other high technology fields. In order to study the electronic properties of diamond more precisely, an AM-response surface model is developed in this paper to investigate the electronic structures of diamond, P-doped diamond and N-doped diamond surfaces in depth. It is shown that there are three forms of charge states in the single vacancy on the diamond surface. When E=0 V, the negative charge energy level is -0.5 mV, the positive charge is 1 mV, and the zero level remains 0. And its energy level is unstable. In contrast, the double vacancy charge on the diamond surface varies depending on the valence band taken by E, and only one charge state exists. When E<0, the diamond surface vacant electron nature is negative charge state. When E>0, it is positive charge energy level. The electronic properties of the P-doped diamond semiconductor material are calculated to have a constant positive charge (1 mV). The electronic property of N-doped diamond semiconductor material is constant negative charge (-1mV).
Because of the current problems of cultural and creative tourism in tourism destination management under the cultural theory perspective, this paper aims to explore the new development direction of cultural and creative tourism. This paper uses the gray-scale correlation method model to construct a correlation degree model, analyze the factors tourists consider in choosing tourist destinations, determine the weights of each influencing factor, and extract the main influencing factors. On this basis, combined with a questionnaire survey method, we analyze the market demand for cultural and creative tourism, tourists’ satisfaction, and the existing problems of the cultural and creative tourism market and put forward suggestions for the problems. In terms of market demand, the highest percentage of tourists’ motivation for tourism is to experience different cultures 60.55%, followed by relaxation 57.35% and appreciation of scenery 55.4%, which shows that the cultural tourism market has great potential; however, there are still many problems in the current cultural tourism, the most prominent being excessive commercialization and loss of cultural authenticity, which accounts for 75%, followed by high ticket prices, lack of creativity in products, however, the service level needs to be improved to 40%, indicating that all these problems need to be paid attention to. Cultural and creative tourism is a form of tourism preferred by tourists, and many problems still need to be further explored.
As one of the important feature categories in urban geographic data, buildings are the key thematic elements to be represented in large-scale urban mapping with the high speed of urban digital construction. The identification and extraction of buildings are of great significance for feature extraction, feature matching, image interpretation and mapping. However, the great variability of building size, shape, color, orientation, etc., in remote sensing images poses a great challenge to building detection. To this end, this paper proposes an algorithm based on multi-feature multi-scale fusion for the automatic extraction of buildings in remote sensing images are represented in the form of roofs. It is difficult to represent all buildings with a single feature because of the different colors, textures and shapes of building roofs. Effective features to describe buildings are proposed, including edge density and edge distribution, brightness contrast, color contrast and other features to describe building edge brightness. We propose effective features to describe buildings, including edge density and edge distribution, luminance contrast, color contrast and other underlying features to describe the edges, luminance and color of buildings, and adding special structural features such as main direction orthogonality and target integrity and symmetry to describe buildings by multiple features together.
Moreover, the K-value nearest neighbor classification algorithm is used to train a series of samples, and the weights of each feature in the multi-feature model are obtained through iterative learning to obtain the multi-feature linear model and calculate the visual saliency of buildings in the sliding window; finally, the proposed algorithm has experimented with several groups of high-resolution remote sensing images respectively, and the multi-scale multi-feature fusion model algorithm is used as the Erkoff random field model to compare the algorithm. The results of this paper show that the proposed multiscale multi-feature fusion model algorithm improves by 10.82% for building classification accuracy extraction and 13.96% for feature selection extraction accuracy, and finally, the comparison from the shape optimization effect figure concludes that the multiscale multi-feature fusion model can achieve better extraction accuracy and practical effect for buildings in remote sensing images, which has certain practicality and It has certain practicality and superiority. It promotes the in-depth application of multi-feature multi-scale combined high-resolution remote sensing image-building extraction in geographic states, road traffic and other industries.t
With the rapid development of the Internet, security issues are becoming more and more prominent, and since most information is transmitted through the Internet today, Internet security is particularly important. When the Internet was designed, only mutual compatibility and interoperability between networks were considered, and security issues were not fully considered. As a result, as the Internet continues to grow, security issues are becoming more and more serious. One of the more difficult attacks is the Distributed Denial of Service (DDoS) attack, which has many forms of attacks, is harmful, and is difficult to identify and defend. Therefore, building a global Internet security protection system to achieve effective protection against DDoS attacks is the main work of this research paper. In this paper, we propose an artificial intelligence DDoS attack protection system, which implements a controller and switch auto-detection model by extending the protocol and establishing an optimization model to realize a low-load and low-latency traffic monitoring scheme; for DDoS attacks. We propose the attack inspection algorithm SCVAE based on Variational Encoder (VAE) and Spectral Clustering. in order to mitigate DDoS attack traffic, the protection system uses the QoS traffic control method, builds the application flow hierarchy model, and filters the attack traffic endured by the system by setting the application flow bandwidth limit as well as the traffic priority dual policy. Finally, a Mininet-based simulation test environment is built to evaluate the model, and different test indexes are set for different system modules to evaluate their actual performance. The results of this paper show that in the network traffic monitoring test, the artificial intelligence DDoS attack protection algorithm can respond to the attack more quickly by reducing the average 73ms per sampling compared with other algorithms; in the attack traffic identification test, the comparison accuracy (P) is improved by 15.14%, the accuracy (AC) is improved by 13.26%, the recall (R) is reduced by 9.23%, and the F1 measurement criteria improved by 23%. The test verifies that the artificial intelligence DDoS attack protection system can achieve real-time monitoring of each performance parameter and also illustrates the feasibility and practicality of the research content of this paper, which strengthens the construction of the technical means of Internet security protection and further enhances the Internet security defense capability.
With the development of information technology, the news media industry has entered the all-media era. Today, everyone is a communicator, and the audience has more diversified channels to obtain news information, but it also leads to the truly useful news being easily overwhelmed. In order to analyze the strategy of news dissemination in the all-media era, this paper analyzes different types of news media platforms and audiences based on big data mining technology. The mining results show that cultural news has the largest share on radio, TV, and video sites, with 27.5% and 57.3%, respectively. Social news had the largest share on news sites, at 29.8%. Political news has the largest share of mobile clients at 27.9%. Economic news has the largest share on social media platforms, with 23.5%. In addition, the news is viewed much more on new media, such as video websites and social platforms, than on traditional media, such as newspapers, magazines, TV and radio. In terms of the exposure rates of different types of news audiences to media platforms, the average exposure rates of newspapers and magazines, TV and radio, news sites, mobile clients, social platforms and video sites are 8.83%, 28.30%, 44.49%, 59.57%, 71.03% and 90.46%, respectively. In the era of full media, news dissemination should focus on applying new communication technologies, enriching the presentation form of news, and selecting reasonable topics for the characteristics of audiences on different platforms. The analysis of news communication strategy based on big data mining can grasp the pain points in current news communication, which is of great guidance for transforming news communication in the era of full media.
As an emerging business model and economic form, the sharing economy is a new trend to promote global economic growth in the future. Public participation is the basic condition for the prosperity and development of the sharing economy and is the basic requirement for the realisation of collaborative governance. Encouraging the public to actively participate in the collaborative supervision of my country's sharing economy has become an inevitable requirement to improve governance efficiency and create a social governance pattern of co-construction, co-governance and sharing. First of all, this paper refers to the rapid development of my country's sharing economy in recent years, which has also brought many negative problems. Secondly, this paper establishes a game model of sharing economy-related enterprises, regional governments and the public to drive the public's shared economy in my country, which forms the driving principle and guiding strategy of collaborative supervision. Through research, it is concluded that the size of the initial probability is proportional to the convergence speed of the game subject's selection strategy; different game subjects have different sensitivities to parameter changes, and the public is more sensitive to the cost and punishment of participating in innovation involving different game subjects The strategy choices between them are mutually reinforcing, and the evolutionary stable strategy is ‘active participation, supervision, active participation. Finally, the simulation experiments are used to verify the results of the tripartite game model constructed in this paper.
Entrepreneurship education is an educational concept and teaching mode which is formed in socio-economic development. Universal entrepreneurship education has both the long-term value of realizing the transformation and upgrading of industrial structure and the practical value of alleviating the employment problem of college students. Therefore, how establishing the innovation and entrepreneurship education model in higher education under the environment of big data analysis is a major issue at present and also a key element to achieving the construction goal of modern higher education. In this paper, the entrepreneurship data of colleges and universities are deeply mined by association rules of the Apriori algorithm and clustering analysis of the FCM algorithm. As a result, an entrepreneurship education model is established and practiced in university classrooms. According to the results of the survey after the practice of the entrepreneurship education model, it can be seen that the number of students’ participation in innovation and entrepreneurship lectures has increased, and the proportion reached 50%. Innovation and entrepreneurship clubs formed on campus and discipline competitions accounted for 16.00% and 18.00%, respectively. College students’ motivations for learning innovation and entrepreneurship education courses are mainly ability enhancement, interest-driven, credit demand, future planning, and influence of others, and they account for 34.00%, 26.00%, 21.00%, 14.00%, and 5.00%, in that order. These indicate that the current group of college students considers the pursuit of knowledge and the improvement of their abilities as the main reasons for undertaking entrepreneurial learning activities. After practicing the entrepreneurship education model, people have increased their knowledge of entrepreneurship theory and are more willing to participate in various entrepreneurial activities.
As teachers struggle with the usage of high-quality digital educational resources, small coverage and weak pertinence characteristics of traditional evaluation methods are the reasons for this. In this paper, three aspects including the connotation, operation mechanism and evaluation of ‘Artisan Workshop’ are analysed, and the classification factors are explored based on the collected educational data. By using these objective characteristics, the application ability of teachers to use digital educational resources is quantified, and the prediction model of sustainable development in ‘Artisan Workshop’ is constructed by adopting random forest regression, extreme gradient boost regression and light gradient boost regression models. According to the application of educational resources and teachers’ ability, this paper proposes an optimized scheme for the sustainable development of ‘Artisan Workshop’, which provides a reference for improving the quality of talent training in China.
Paper-cut elements in the design of boat space can effectively improve the homogenisation tendency of existing boat space design, effectively enhance the characteristics of traditional Chinese culture and enrich the development ideas of boat space design. Therefore, based on the Chinese folk art of paper cutting, this paper combines theoretical analysis and empirical research to deeply analyse the artistic expression of paper-cut elements in the spatial design of boats. This paper mainly studies the artistic integration of paper-cut elements in the decorative design of boats and the artistic integration of paper-cut elements in the practical design of boats. Through the calculation and analysis of the sparse autoencoder algorithm model, it can be seen that the decorative integration of paper-cut elements in wallpaper is 82%, which is higher than that of traditional materials (24%). The integration of paper-cut elements in the space design of cabins and guest rooms is as high as 97% and 94%, respectively, which is far better than the integration of traditional materials in the space design of cabins and guest rooms. This shows that the application of folk paper-cut elements to the space design of boats not only highlights the theme of boats but also enhances the cultural value of boats.
Tea culture is the main component of Chinese traditional culture, and the analysis of tea culture dissemination paths can promote the process of Chinese traditional culture dissemination to the outside world. This paper standardizes the tea culture dissemination paths based on the principal component analysis method. The correlation matrix of the standardized data is tested for sampling suitability, and the eigenvalues and eigenvectors are calculated to derive the principal components. The variance contribution rate and the cumulative contribution rate of the variance of the principal components are calculated, and then the scores of each principal component are derived and evaluated comprehensively.

This paper addresses the optimal decisions and channel coordination issues in a green supply chain composed of a socially responsible manufacturer and a fair-mined retailer, where the manufacturer invests in advanced facilities/technologies to improve green quality of products, and the retailer exerts marketing effort to enhance market demand. We develop supply chain models under three scenarios: centralized system, wholesale price (WP) contract without fairness concerns, and WP contract with fairness concerns. Our results show that the retailer’s fairness behavior further causes a benefit for herself, while the manufacturer and the total supply chain to suffer. Moreover, a revenue-cost-sharing (RCS) contract is introduced to coordinate supply chain. We prove that a win-win outcome is reachable, and the RCS contract is applicable in practice.
Customer portrait is the customer information that is labelled and digitised. Collecting and studying consumer data is highly helpful to enterprises because it empowers them to use these data to locate target groups and meet various customer needs. With the continuous rise of the e-commerce market, major e-commerce websites list providing customer value and being data-driven as company values. Traditional customer portraits rely excessively on objective and past experience; so, a simple but powerful customer portrait system is required to make the customer analysis platform simple and intelligent, and to make the data accumulated at ordinary times bring practical value to e-commerce companies. Based mainly on addressing this requirement, this paper proposes an effective customer portrait system for e-commerce. First, the research background and significance is expounded, which lays a theoretical foundation for this research. Then, the customer portrait system is designed, including the overall design scheme and functional framework of the system. The improved FCM algorithm is used as the basis for building the customer portrait model, and the performance of this algorithm is analysed and compared with that of the improved algorithm used in this paper.
In order to give full play to the application of big data in film and television media and imaging in the cloud era, this study proposes a communication-efficient distributed deep neural network training method based on the DANE algorithm framework. The DANE algorithm is an approximate Newtonian method that has been widely used in communication-efficient distributed machine learning. It has the advantages of fast convergence and no need to calculate the inverse of the Hessian matrix, which can significantly reduce the communication and computational overhead in high-dimensional situations. In order to further improve the computational efficiency, it is necessary to study how to speed up the local optimization of DANE. It is a feasible method to choose to use the most popular adaptive gradient optimization algorithm Adam to replace the commonly used stochastic gradient descent method to solve the local single-machine suboptimization problem of DANE. Experiments show that Adam-based optimization can converge significantly faster than the original SGD-based implementation with little sacrifice in model generalization performance. With the increase of sampling rate, DANE-Adam significantly outperforms the DANE method in terms of convergence speed, and at the same time, the accuracy can be kept almost unchanged, which are 0.96, 0.88 and 0.75, respectively. This shows that Adam-based optimization can converge significantly faster than the original SGD-based implementation with little sacrifice in model generalization performance, with significant potential value.
Under the influence of the new energy strategy, the new energy vehicle has developed vigorously. As an important supporting infrastructure, the rationality of its location construction has become the key factor for the popularization of the cars.

Thus, the multi-objective optimization model can be simplified, and the chicken swarm algorithm is used to settlement this question.
With the rapid development of computer science and technology, there is an increasing diversity observed in the use of electronic computers. Users browse interactive content such as text, images, audio, video, etc. The increase of the interactive interface results in a slow interface response and affects the user experience. Therefore, this paper mainly studies the user interface under the multi-dimensional optimisation of the Rhino/GH platform, and introduces the long short-term memory and gated recurrent unit algorithms in the visualisation part for optimisation; the study results suggest that the overall response time is 50% but lower than the traditional interface, and the time fluctuation is within 23.7%, which is 23.6% but lower than the traditional 47.3%. When interacting with multiple interfaces, the interaction interface optimised by the Rhino/GH platform maintains a fluctuation range within 29.2%, and the time increases by 13 ms, showing excellent stability and efficiency.

This shows that the development of industrial robot simulation in water environment monitoring is promising and feasible.
Art and design are creative activities humans engage in to achieve certain purposes. The multiple characteristics of art and design also put forward more requirements for developing higher education art and design education. In this paper, starting from the problem that the multiple characteristics of art and design make it difficult to evaluate the teaching quality, the FAHP-FCE evaluation system is proposed to score the quality of art and design talents training. Firstly, fuzzy hierarchical analysis (FAHP) is used to construct a judgment matrix to filter out evaluation indexes. Secondly, multi-level fuzzy comprehensive evaluation (FCE) is used to evaluate the evaluation indexes to obtain the score. Finally, conclusions were drawn by comparing the effectiveness of the two teaching models. The research results show that the effectiveness of the FAHP-FCE evaluation system-based art and design talent training teaching model is assessed as 83.47 points, which is 34.11% more effective, 23% more design ability, 31% more learning ability and 26% more hands-on ability than the traditional teaching model. The talent cultivation model in this paper enables students to master abstract design ability, helps to expand the field of creative thinking, enriches the language of modeling and artistic imagination, and improves comprehensive design ability and learning ability.

In order to improve the recognition accuracy of symphonic music contour, this paper constructs an intelligent music main melody recognition system based on artificial intelligence technology to make melody recognition with certain search adaptation capabilities. Based on the traditional melody recognition system, the fundamental tone sequence of symphony fragments is obtained by using the fundamental tone extraction and short-time autocorrelation function in the melody contour feature extraction algorithm, which is transformed into the melody contour sequence after regularization and merging to determine the similarity of the music melody signal itself. The wavelet transform method and radial basis function algorithm are used to improve the defects of monophonic discrimination in the traditional recognition model so that the artificial intelligence technique can effectively fit with the symphony recognition model of music melody contour. The experiments show that: The average recognition accuracy of the AI-based music melody recognition system is 90.5%, which is significantly better than 69.5% of Sound Hunter software and 76.5% of Shazam software. For the five monophonic chords, the system’s recognition accuracy is as high as 98.3%, especially in the field of hanging chords with significant recognition effects. It can be seen that the artificial intelligence-based music main melody recognition system provides a scientific and authoritative recognition means for the dissemination and development of symphonic music and is conducive to improving the recognition accuracy of symphonic melodies.
Constantly promoting theoretical innovation is the key to the perpetual vitality and vigor of Marxism. Marxist theory interpretation can provide new perspectives, new assertions, and new requirements for adhering to the basic principles of Marxism in line with the requirements of the times, national characteristics, and practical needs, and is the main basis for the formation, development, and renewal of the theoretical paradigm. Therefore, Spring+SpringMVC+Mybatis is used as the back-end development framework of the decentralized Internet to establish the decentralized Internet model used for interpreting Marxist theories. It is realized through the stages of theoretical semantic representation, multi-dimensional feature extraction, and classification. According to the multidimensional interpretation effect, the classification recall of the theoretical interpretation dimensions obtained after using the decentralized Internet model increases from 59.15%, 58.84%, 61.21%, 62.79% to 69.49%, 72.03%, 71.87%, 72.9%, and the average running speed of 9.21s decreases significantly to 3.84s. Portability, accessibility, interpretation completeness and contextual integration, depth of understanding indexes of ranking, accessibility, interpretive completeness, and contextual integration, depth of understanding, interpretive adequacy, and six-theory coverage reached 89.26%, 91.45%, 90.75%, 92.84%, 93.23%, 96.29%, and 99.12%. It shows that the decentralized Internet interpretation method of Marxist theory can grasp the scientific connotation and inner mechanism of theoretical development, trace the origin from ideas and perspectives related to the concept and summarize and interpret the background, reality, gist, content structure, and its contemporary significance under the new era discourse, so as to better implement and practice Marxist theory.
In order to explore the development path of Hunan embroidery under the vision of artificial intelligence, promote the digital regeneration and database construction of Hunan embroidery stitches, the communication, and interaction between Hunan embroidery brands and the public, and create more possibilities for revitalizing the culture and industrial development of non-heritage Hunan embroidery. In this paper, a mechanics model of Hunan embroidery stitch is established based on the finite element idea under the view of artificial intelligence. The single yarn in the yarn is regarded as a frictionless articulation of some rows of elastic rods with a circular cross-section. The elastic rod can only be subjected to axial force without a moment, and it is a uniform, continuous, and completely elastic isotropic body. Using the displacement method, the displacement of the unit node is taken as the basic unknown quantity, the displacement in the unit is assumed to be linearly distributed, and the displacement of any node in the unit is obtained by linear interpolation. The strain, stress, and stiffness matrices of the elastic rod unit are derived, the equilibrium equations are given, and a database is established. The results of the study showed that consumers of all age levels thought that the patterns representing Hunan embroidery mainly include Hunan characteristic landscapes, portraits of Hunan great men, traditional flowers, birds and animals, and totems of Chu culture, etc., among which Hunan characteristic landscape accounted for 54% of the largest proportion. It provides a development direction for the inheritance and protection of Hunan embroidery skills.
The teaching mode of the innovative automotive manufacturing process is to improve students’ automotive manufacturing technology. In this paper, firstly, the basic principle of the ant colony algorithm is introduced, and the ant colony algorithm is improved and optimized by heuristic function, state transfer probability and pheromone update rule. Then the optimized ant colony algorithm is used as the base algorithm for constructing the ADDIE model. After establishing the ADDIE model, two dimensional indicators of the teaching mode of the automotive manufacturing process, i.e. teaching objectives of the basic course and application course, are mined for the example of the automotive manufacturing process course of L school. The two example indicators proposed are analyzed and illustrated using the example data.
Regarding the basic course teaching objectives, the mean values of A, B, C and D evaluation indicators accounted for 47.73%, 21.46%, 20.17% and 10.65%, respectively. Regarding the teaching objectives of the application courses, the mean values of the four evaluation indexes of A, B, C and D account for 50.24%, 15.75%, 21.05% and 12.96%, respectively. The innovative teaching mode of the automotive manufacturing process based on the ADDIE model is beneficial for students to learn technology in a new way and also for delivering high-quality technical talents to automotive manufacturing enterprises.
Wear of seal materials is a widespread problem in the aerospace, petrochemical, and electric power fields, leading not only to low efficiency of mechanical equipment, but also to increased energy consumption and reduced safety performance. Therefore, this paper establishes the SCA-wear model based on the tensile constraint algorithm to calculate and analyze the friction and wear performance of mechanical seal materials. The friction coefficients of different loads at 200°C and 10 min after the test time stabilize, and fluctuate in the range of 0.35 at 30N, 0.26 at 70N, and 0.48 at 90N. The frictional wear of the C/C composite mechanical seal material is at least 15.6%. The reason is that it is composed entirely of carbon. It has many advantages of carbon and graphite materials. Therefore, the frictional wear of the C/C composite seal material is low.
Researching the past empirical studies, we find that the empirical results of using data from the same or similar stages of economic development tend to be very close; however, there will be some discrepancies when comparing the empirical results of data samples at different stages of development. In order to explain this phenomenon, a theoretical analysis is made on the regional differences in the impact of population ageing on national saving. By analysing the areas considered in this paper as being in different stages of economic development, the combined effects of population ageing on the national saving rate are different. In order to verify the above conclusions, the thresholds and threshold effects are estimated and tested through the threshold model. The results show that the impact of population ageing on the savings rate will be different due to different levels of economic development. When per capita income is below the threshold of 9001.69, population ageing has a greater negative impact on the national savings rate. When per capita income is above the threshold of 9001.69, the negative impact of population ageing on the national saving rate is smaller.
The economic benefit of enterprises is an effective index to measure the economic activities, which forms the basis and starting point. Therefore, in this paper, the traditional analysis methods of enterprise in terms of economic benefits are compared and based on its evaluation principles, the advantages, theory and realisation process of the kernel function in enterprise economic benefits analysis are analysed. Then, different kernel functions are selected to analyse the total output value, product sales rate, sales revenue, total profit and total profits after taxes of five enterprises, and their economic benefits are evaluated by the cumulative contribution rate of principal components. Finally, the mixed kernel function based on the combination of polynomial kernel function and Gaussian kernel function is used to optimise the analysis effect, which is meant to help enterprise leaders make more scientific decisions and lay a foundation for the sound development of enterprises.
In order to have a better product display and thus attract consumers’ purchases and increase the economic benefits of the enterprise, in this paper, we propose a deep learning model for brand 3D image design. A feedforward neural network that estimates the error of previous layers based on the error of the output layer assigns the convolutional kernel weight parameters of the network in the interval and stops when the error reaches a preset accuracy or reaches a preset maximum learning count. The locally-aware convolutional neural network acquires local features that are finer than the global features and outputs the feature maps of the convolutional layers after passing the activation function to calculate the sensitivity of the sampled layer units. Given the sensitivity information of the feature map, the gradient of the kernel function weights is obtained, and the updated parameters are trained to achieve feature map recursion and solve the image boundary problem. A 3D recurrent neural network is constructed using data-driven multiple or single images, transformed into a low-dimensional feature matrix, processed with 3D pixel data, extracted perceptual features, and generated high-resolution images. The analysis of the results shows that the CD value of the used model is 0.477 and the EMD value is 0.579, which makes the constructed 3D images with more obvious detail levels and more accurate structural design, while the model of Pixel2Mesh focuses more on surface information, so the generated model is more realistic and closer to the real image.
Digital humanistic knowledge production emphasises the importance of a strong knowledge production community and differentiates from traditional knowledge production models, which include aspects such as online and cooperative knowledge development. The digital humanities knowledge production community model is already widely acknowledged. However, the features and characteristics of digital humanistic knowledge production under natural language processing are controversial. This research presents a wordVEA digital humanistic knowledge production feature mining approach based on a word2vec and variational self-encoder (VAE). The knowledge production characteristics of digital humanistic are primarily defined by the coexistence of a knowledge production structure and boundary blurring, as well as interdisciplinary collaboration thematic cohesiveness and broad horizon, as determined by the research results which effectively address the question of the characteristics of digital humanistic knowledge production through application of the word VAE method.
With the rapid development of Internet technology, the field of hotel management has begun to carry out informatisation construction, through which the management level and operational efficiency of hotels can be improved. The traditional hotel management work with a complex structure and cumbersome process is facing huge challenges. Therefore, this paper aims to design, develop and implement a small and medium-sized hotel management system based on customer relationship management (CRM), according to the characteristics of small and medium-sized hotel management. Management and system setting management of small and medium-sized hotels can reduce the hotel operating costs and increase the profitability by using this system. The department and employee performance appraisal can be divided into four dimensions, finance, customer, internal business process, and learning and growth for job analysis and design, using the key performance indicator method to lock key appraisal indicators, and ignore or omit irrelevant or insignificant indicators. Then the analytic hierarchy process is used to scientifically determine the indicator weights. The Delphi and in-depth interview methods are used to complete construction of the performance appraisal system, and the constructed CRM performance management system is used to achieve the hotel's strategic goals, thus completing the fundamental goal of using the CRM model. The slacks-based measure model is based on the assumption of variable returns to scale, considering that the input redundancy and output deficiency of ineffective decision-making units are measured based on their slack. This paper defines input inefficiency as the ratio of input slack to actual input, and output inefficiency as the ratio of output slack to actual output. The total input inefficiency rate of the hotel industry in China's ineffective provinces and regions is 0.458, while the total output inefficiency rate is 0.077, indicating that if the total investment in the hotel industry is reduced by 47.8% on average and the total output is increased by 6.9% on average, the hotels in these ineffective provinces and regions can all be relatively effective. Finally, the overall performance of the system will be evaluated, and a set of safe, convenient and friendly hotel management system will be developed.
With the rapid development of the market economy, a large number of enterprises provide many jobs with different requirements. In the traditional application process, college students need to search the job requirements of each company one by one to match their own needs and conditions, which not only requires a lot of time and opportunity costs, but also has poor matching degree. This paper uses the recommendation and machine learning algorithms to match and optimise the job characteristics and needs according to the professional type, interest and specialty, employment area and personal preference of college students through the algorithm, and recommends suitable positions for college students to improve their success in application and increase their employment satisfaction rate.
In the construction of intelligent teaching resources, a large number of resources are collected to meet the teaching needs, and its organisational structure, resource content and teaching quality are not fully recognised. At present, there are few studies on the performance evaluation of intelligent teaching, and the research angles are also different. Based on this, this paper constructs the application performance evaluation model of intelligent teaching resource organisation mode. Based on the simple analysis of intelligent teaching research and the development of big data mining algorithm, this paper uses data mining algorithm to realise resource mining, uses ant colony algorithm and association rules to mine information, carries out student evaluation on this basis, and uses ID3 algorithm to construct decision tree to analyse the main factors affecting teaching. Then the performance evaluation model is built, and the concept of fuzzy mathematics is introduced to realise the comprehensive evaluation based on analytic hierarchy process. Finally, simulation tests and experiments are used to analyse the effectiveness of the algorithm and the application of the model. The results show that the data mining algorithm based on association rules can mine more information and shorten the running time. The performance evaluation model based on fuzzy comprehensive evaluation can be applied to the evaluation of intelligent teaching, find the shortcomings in teaching, and confirm the effectiveness of the model.
In the process of designing animation characters and background elements, there may be a high degree of visual blur, resulting in a strong sense of picture distortion, and it is easy to expose the incomplete picture. Accordingly, this paper proposes to use directional derivatives to deal with animation-like visual problems. This method is based on the theoretical basis of directional derivatives, combined with the current mathematical methods of animation character and background element design, and defines the important role of directional derivatives in animation and background design, and more effectively enhances the visual results of animation characters. In the research of clarity and distortion, this paper uses directional derivative derivation as the cutting-in method to test the algorithm for visual simulation and restoration of animated characters and background elements so that the algorithm can be used for each animation character and background element. The defect point is calculated, and the clarity and self-healing ability of the video itself are improved by the influence of the mathematical parameters of the surrounding known points on itself and the key variable of the directional derivative in the field. The results show that the directional derivative can play a role in promoting sublimation in the design of animated characters and background elements.
Studying the concept lattice of intuitionistic fuzzy language can not only enable an intuitive expression of the relationship between objects and attributes but also ensure the effectiveness of information, and it thus provides a new idea for the development of artificial intelligence. Therefore, in this paper, the rule extraction method is studied based on the concept lattice of intuitionistic fuzzy language. By combining the formal context of intuitionistic fuzzy language with the context of decision formal, the formal context of intuitionistic fuzzy language decision is put forward and the rule extraction method under this context is constructed. The problem of decision making in real life can be solved through the weighted similarity in the formal context of intuitionistic fuzzy language.
The manufacturing industry requires a unique recommendation system to suggest products and raw materials, but its performance is often poor in massive data environment. In order to solve the similarity connection problem of large-scale real-time data, the optimised incremental similarity connection method which is used to deal with streaming data can be used to concisely obtain the longest common additive sequence of two given input sequences. This paper, on the basis of the recursion equation, applies a very simple linear space algorithm to solve this problem and adopts new states to carry out similarity connection of incremental data. The experimental results demonstrate that this method can not only ensure the accuracy of real-time recommendation system but also greatly reduce the computed amount.
Today, corresponding to the new wave of internationalisation and integration, education is also subject to rapid and innovative changes. Accordingly, detailed research is undertaken in the present study on innovative teaching strategies that can be developed, under the background of artificial intelligence, to familiarise college students with the ability to fluently express their ideas in English. The research shows that among the factors affecting the quality of English teaching, teachers’ teaching methods, English teaching environment and students’ independent learning ability account for high weightage, which are 54%, 31% and 11%, respectively. Through the model of college students’ English teaching innovation strategy, it can be seen that the teaching method, teaching environment and autonomous learning method are the most feasible methods that can be employed in crafting a students’ English teaching innovation strategy.
In recent years, artificial intelligence has gradually become the core driving force of a new round of scientific and technological revolution and industrial transformation, and is exerting a profound impact on all aspects of human life. With the rapid development of Internet big data and high-performance parallel computing, relevant research in computer vision has made significant progress in the past few years, becoming one of the important application branches in the field of artificial intelligence. The exercise of image classification forming part of computer vision tasks involves a large amount of computation, and training based on traditional deep learning (DL) classification models typically involves slow training and low accuracy in many parameters. Thus, in order to solve these problems, an image classification model based on DL and SAE network was proposed. Firstly, the main research of computer vision task-image classification is introduced in detail. Then, the combination framework of deep neural network and SAE network is built. At the same time, the deep neural network was used to carry out convolution operation of the parameters learned by SAE and extract each feature of the image with neurons, so as to improve the training accuracy of the deep neural network. Finally, the traditional deep neural network and SAE network were used for comparative experiment and analysis. Experimental results show that the proposed method has a certain degree of improvement in image classification accuracy compared with traditional deep neural network and SAE network, and the accuracy reaches 97.13%.
In recent years, the investment amount of university engineering construction has been increasing significantly, and the establishment of scientific and reasonable cost management system has become particularly important in the investment control of engineering construction. This paper explores the investment control of university engineering construction and designs the basic framework based on three parts: whole process cost control, full caliber cost audit and full gradient grading management. With the help of BIM, we build a cost management system, which is divided into the planning stage, bidding stage, mid-construction, until the completion of the collation of cost data, extraction and preservation of cost indicators. After establishing a full range of cost management systems, the adjacency matrix X algorithm and functions are used to calculate. The experiment proves that: the investment estimate before the project construction affects more than 75% of the overall investment, and the all-round cost management system built based on BIM can make the investment estimate accurate and stable at 75%, and the negotiation change rule based on this is to save nearly 25% of the investment funds. The comprehensive cost management system has a comprehensive and detailed grasp of the cost process of specific construction projects and specific issues during construction, fully protecting the university’s investment interests.
In recent years, the development of artificial intelligence technology and theory has been rapid, and the application in language science has been gradually comprehensive and diversified, especially the accuracy rate of artificial intelligence for Chinese language is up to 90%. In the era of artificial intelligence, the effect of different structures and parameters of arithmetic models on Chinese language recognition varies greatly. Language science is an important research area for realizing machine-human communication, and accurate comprehension of the meaning of linguistic expressions is the key to realize communication. In this paper, we construct a speech system that is different from the traditional stable time series for the irreplaceable characteristics of artificial intelligence technology to improve Chinese language ability. A dynamic Bayesian network (DBN) is used for modeling and analysis, and a DBN construction method is investigated to import a hidden Markov model in a speech recognition system to reveal the interactions between nodes within multiple time slices. The accuracy of dynamic Bayesian networks in Chinese dialect inference algorithms is demonstrated using Matlab simulations to characterize the reliability of speech features using a speech spectrogram. It proves that artificial intelligence technology and Chinese language science are complementary and mutually reinforcing, showing a good and rapid development trend.
In order to improve the ability of micromechanical sensors to update data-matching nodes in real-time and speed up the establishment of a neighbor relationship between nodes, this paper proposes a personalized recommendation algorithm for micromechanical sensors based on the cloud model to improve the stability and real-time performance of micromechanical sensors. The algorithm uses the service attribute values of the cloud computing model and cloud clustering method to set feature term labels and establish a cloud service similarity matrix so as to meet the user-matched manufacturing service requirements. The intra-class clustering technique is applied to measure the clustering effect, and the evaluation function of each clustering number is calculated on the basis of considering the time sequence to determine the best clustering result to complete the personalized recommendation path for micromechanical sensors. To verify the application effect of the personalized recommendation algorithm for micromechanical sensors based on the cloud model, experiments are conducted. The results show that the recommendation algorithm in this paper can always control the node energy consumption below 2.5×103, and the average discovery delay is stable between 41-43 seconds. And the sensor response time is 12.1 seconds, and the average absolute deviation value is 0.23, which is nearly 1.3 times smaller than 0.53 and 0.52 of the collaborative recommendation algorithm and hybrid recommendation algorithm. It can be seen that the recommendation algorithm in this paper solves the problem of excessive neighbor discovery delay in the communication process of micromechanical sensors and effectively improves the personalized recommendation performance of micromechanical sensors.
In order to reduce the vibration damage of the engine and improve the automatic transmission adjustment performance of the automobile, an automatic transmission system based on torsional damping is constructed in this paper to optimize the hardware function of the shift speed. The torsional damper is used as the core control element to reciprocate the automotive mechanical automatic transmission system, and the calculation method of torsional vibration analysis of the crankshaft shaft system is used to determine the indexes of rotational inertia, stiffness, and damping parameters of torsional vibration. The damping coefficient values are set near the equilibrium point, and the loss factor of the automatic transmission system is signal processed to obtain the best damping effect. Using the intrinsic frequency as the central processing unit of the automatic transmission system, the differential equation is used to calculate the excitation torque vector of each cylinder of the engine, and the characteristic module of the automatic transmission system is developed. The tests showed that the cylinder burst pressure of the automatic transmission system with the torsional damper reached a maximum of 67.9 pressure at 4800 amp. The crankshaft front-end torsional angle of the 4th-order main harmonic excitation reached a maximum of 0.57 degrees, which exceeded the engineering allowance of 0.2 degrees and reduced the automatic shift shock by about 28.36%. It indicates that the torsional damper can improve the control performance of the automatic transmission system, which is conducive to enhancing the stability and self-adaptive capability of the transmission adjustment.

Then, we build a BP neural network combined with a deep LSTM neural network, use the BP network algorithm to select the input variables to reduce the dimension and complexity of the model, and use the selected variables as the input of the deep LSTM network. At the same time, deep LSTM is used to perform high-dimensional deep memory learning features on the selected variables. Finally, the model is separately experimented in computer vision. The experimental results show that the present model and other single models can be selected by BP neural network variables in computer vision applications, which can effectively reduce the complexity of the model and improve the generalisation ability of the model, so that it can be used in computer vision research.
The analysis of the psychological impact of the spread of Yangming studies in Japan on the Japanese people is to enable Yangming studies to be better developed in Japan. Based on big data analysis technology, this paper constructs a hybrid data analysis model using the EM algorithm and proposes performance evaluation indexes for the model. Under the EM data analysis model constructed in this paper, the example indicators of the Japanese people’s psychological impact in disseminating Yangming studies by big data analysis are explored, i.e., the psychological acceptability of the dissemination method and the psychological and moral construction impact. Regarding the dissemination method, the Japanese people are more receptive to disseminating Yangming studies in Japan through “learning rules”, with an average percentage of 39.37%. Regarding psychological and moral construction, 90.22% of the Japanese people believe that disseminating Yangming studies can promote self-improvement of value standards and correct self-examination. Based on the big data analysis, we can effectively see from the data the impact of Yangming studies on the audience in the process of dissemination, and improve the scope of Yangming studies dissemination according to the data feedback, so that more people can recognize the idea of unity of knowledge and action.
Because of its large structure and strong bearing capacity, large rolling bearings are mainly used on low-speed and heavy-duty occasions. At present, the analysis and Research on large rolling bearings include load distribution, bearing capacity, bearing service life and bearing structure optimisation. Taking the large four-point contact bearing as an example, this performance studies the method of channel structure parameter design and life analysis.

We can see that in terms of attention, relevance, confidence and satisfaction, the results show that ARCS motivation model is effective in college oral English teaching.
The Internet of Things, as an important part of important data aggregation, forwarding and control, often leads to objectivity errors due to the huge and complex received data. Based on this, this paper introduces GRU, LSTM, SRU deep learning to optimize the data received by the Internet of Things, and selects the most suitable communication mode optimization algorithm. The experimental results show that the accuracy errors of GRU, LSTM, and SRU algorithms show a downward trend, from 0.024 to 0.010%; the training time is reduced by 254 minutes, and the training speed is increased to 86%, indicating the excellent performance of SRU deep learning in IoT gateways.
With the advent of the artificial intelligence era, the traditional methods of online learning can no longer meet people's personalised needs. Take the English vocabulary memory APP, which is widely used in the market of learning software, as an example. At present, there are various factors that make it difficult for learners to improve their learning efficiency, reduce their learning enthusiasm and enhance their learning effects. Therefore, in this paper, the application of machine learning algorithm in intelligent recommendation of English vocabulary learning is studied, and an intelligent recommendation system for English vocabulary learning based on crowdsensing is established. In its functional module, machine learning algorithms such as clustering algorithm, word vector training and collaborative filtering recommendation are used to realise the intelligent recommendation in the system. Finally, accurate resources of recommendation for user groups with different needs, interest characteristics and abilities improves the efficiency of English vocabulary learning.

In order to have a qualitative improvement in the education management of universities in the background of the era of big data technology, it is necessary to integrate information technology and technological means in the process of education management. Based on this background, this paper constructs an informatization education management platform. In the process of platform architecture, the cloud storage module obtains the exact nearest neighbors by the time factor, optimizes the construction process by using the weighting function and hybrid coordination filtering algorithm, and simplifies the teaching management process. In the teaching management system, the fixed rules of the feature selection algorithm are used to achieve teaching resource selection prediction in the optimal feature subset and establish the best classification surface. Finally, the performance of the platform proposed in this paper is verified from two levels: resource recommendation and education management. The experimental results show that the MAE (Mean Absolute Error) value of this platform is always under 0.7, with a mean value of 0.523, and the experimental teaching resource recommendation effect is better than that of the IE virtual experiment teaching platform and data platform. And the maximum number of visits that the platform can bear is 884, and the maximum amount of government processing can reach 839, which is much larger than the number of 800 users of experimental teaching in the university and fully meets the needs of university education management.
Internet information capacity is expanding and developing at a high speed every day. The huge amount of information data involves many problems, such as resources could be scattered, overlapped and confused and thus difficult for users to timely and accurately capture information suitable for them, especially in the field of education. Through the MRLG Rec algorithm, the following processes can be carried out: deep processing, characterisation of data to generate unique individual portraits of user information and to store education resource databases at the same time and analysis of recommendation system to provide users with more accurate high-quality education resources, thus forming a two-way unblocked and efficient information transmission closed-loop, which help learners find teaching resources of the time. It also has screening channels of high-quality educational resources. Through the analysis of experimental data, it is concluded that the algorithm improves the user viscosity of human-computer interaction in the teaching resource recommendation system.
Wushu Sanda is a practical fighting skill and a new modern competitive event. Under certain conditions, they use kicking, hitting and wrestling as the main means according to certain rules. A good Sanda athlete should have good physical quality and special skills. Given the continuous change and revision of Sanda rules, the means to reduce the number of injuries sustained by athletes, tap their potential and prolong their sports life has become an urgent priority. During the training process, the coaches should use a guided and inspiring educational model to enable athletes to think positively and rationally. It is necessary to clearly understand the physical conditions of the body, combine the special characteristics of the Sanda movement and adopt effective prevention and recovery methods. This paper takes the sports fatigue of Sanda athletes as the research goal. To this end, we use physical, biochemical and psychological indicators and means to comprehensively monitor athletes’ sports fatigue. In order to improve martial arts training, improve the physical health of martial arts athletes and improve the athletes’ competitive level.
To identify the influence of the lack of audit information on the decision-making of securities investment, a method to analyse the impact of missing audit information on the decision-making of securities investment based on two Logistic regression models was proposed in this paper. Assumptions about the impact of missing audit information on decisionmaking of investment were developed. Two Logistic regression models were established to analyse the impact by using Logistic regression functions. Variables in analysis models were designed to solve the Logistic regression models with an ADMM algorithm, so as to analyse the impact of missing audit information on the decision-making of securities investment. The analysis of the impact of missing audit information on the securities investment decisions based on two selected models yielded the following results: (1) The lack of audit information was positively correlated with other decisions except the standard effective securities investment decisions; (2) To improve the problem of audit information missing, as the time went on, there was a strong correlation between the lack of audit information and the effectiveness of securities investment decisions; and (3) The lack of audit information was negatively correlated with the effectiveness of securities investment decisions.
This paper aims to construct a multimodal poetry translation corpus for easy retrieval by poetry translation researchers and enthusiasts. In this paper, we combine the AdaBoost model and ELM network and propose the ELM-AdaBoost method to put the existing poetry translation corpus into the ELM network for learning, to obtain several weak predictors, and then use AdaBoost for classification iteration, and update the weights according to the prediction sequence weights, and then obtain strong predictors, and finally construct a multimodal poetry translation corpus. The search of this corpus shows that, in terms of the ideographic performance of the translations, the ancient poems perform the best, followed by the five-line stanzas, with mean evaluation scores of 83.2 and 80.9, respectively. The seven-line stanzas have the best phonetic performance, with an average rating of 73.2. The rhetoric of five-verse poems was the best, with an average rating of 63.5 marks. The overall translation effect is relatively poor because the meaning is often difficult to account for, or there is a cultural gap in the translation of poems. The multimodal translation corpus based on the AdaBoost model is a powerful tool for poetry translation research, which provides strong data support for Chinese poetry translation research and is of great significance for Chinese poetry culture.
Image inpainting aims to fill the undetectable domain and has been studied using deep learning in recent years. This study investigates smoothness-informed convolutional neural network models for image inpainting. The total variation (TV) is considered and local smoothness constraints are also explored in this study. The local smoothness constraint is conducted by the fidelity of the low-order derivatives on mostly connected parts of the given image at training stage. Unlike most neural network-based inpainting methods using numerous images for training, only a single local image containing the domain to be filled is required for the whole training here. The convolutional neural network accepts the image and is trained using detectable data. Computational results indicate that the local smoothness constraint can conduct a more satisfactory inpainting in comparison to usual TV-based one. We also demonstrate how a deep learning approach is used to solve the Euler-Lagrange equation-based inpainting.
This thesis is based on data obtained from conducting investigations concerning financial literacy among rural households in Shaanxi and Yunnan in 2016. The study chooses the Heckprobit model based on the instrumental variable for conducting its analysis, identifies the influencing factors of rural household credit demand, especially the credit constraint, and conducts high-spot reviews on the effect and heterogeneity of financial literacy. The research shows that the financial literacy has an obvious positive impact on the credit demand, i.e. the higher the financial literacy level of the rural household, the bigger the credit demand that the rural household will have; the financial literacy has an obvious negative effect on the formal credit constraint, without any prominent impact on the informal credit constraint or the overall credit constraint. It means that promotion of the rural household’s financial literacy level can only ease the formal credit constraint, and worse, the higher the financial literacy level is, the weaker the formal credit constraint of the rural household will be.
For a long time, the situation of students’ learning in physical education (PE) was not optimistic, especially the basic movement learning after class, which lacked effective online learning tools. With the in-depth research of deep neural network and the rapid development of computer hardware, the artificial intelligence technology based on deep learning has performed well in the field of basic teaching. Therefore, in this paper, an intelligent teaching system of basic movements in PE is designed. First, the information of coordinate points is collected according to the Gaussian model, and the pose of students is estimated by OpenPose. Second, the overall architecture and functional modules of the system are designed. Finally, the deviation limbs that affect the standard of overall movements are identified by the matching algorithm, which realises the evaluation and feedback of basic movements in PE. Through this teaching system, teachers can obtain the learning situation of students’ movements, and students can adjust their movements through the feedback, which achieves the convenient interaction of PE teaching.
In the context of vocational education reform, with the rapid development of big data and internet technology in recent years, coupled with the increase of employment pressure in China, universities have paid more attention to students’ employability competitiveness and paid attention to the reform and innovation of employment education and management work around the goal of higher vocational education personnel training. Based on the theory of the GRU employment education model and supported by big data internet technology, this paper uses a questionnaire survey and semi-structured interview to conduct exploratory factor analysis and validation factor analysis on the constructed employability evaluation index system by using empirical analysis method and finally constructs an employment education model for higher vocational students. At present, compared with the nearly 100 years of exploration history of employment education in colleges and universities in developed countries such as the United States, the employment education of college students in China has a relatively short history and is still in the exploration and development stage. The combination of vocational education reform and big data and internet technology will create a good environment for the future development and growth of students. Therefore, it is necessary to improve the relevance of employment education and management from the perspective of students and teachers in the “Internet+” environment and provide some new ideas to solve the outstanding problems in the employment education of college students so as to ensure that students can enter and adapt to the workplace smoothly after graduation.
The talent training evaluation model not only helps to evaluate the talent itself but also provides feedback on the content of the talent training evaluation. Therefore, this paper establishes an efficient and intelligent talent training evaluation model for accounting professionals based on the logarithmic cycle power law model. The main content of talent training evaluation is set as general knowledge skills, professional thinking, and values. The log-periodic power-law model and the least squares method are combined to reduce the dimensionality of the nonlinear parameters of the judging content and to quantify the judging of intelligent accounting professional talent training in universities, which is convenient for the calculation of linear functions. With the help of log-periodic power-law oscillation to prove that talent training is changing in a cyclical pattern, the feasibility of its prediction is demonstrated. The study shows that the talent cultivation judgment model constructed based on the log-periodic power-law model is very accurate, especially in talent cultivation value judgment prediction. The model achieves zero error in the prediction of some data, and the maximum error between prediction and actual is only 6%. In the judgment of general knowledge and skill cultivation, the maximum error between the prediction and the actual score of the model is no more than 2 points. This shows that the talent development evaluation model based on the log-periodic power law model can make accurate predictions of talent development evaluation.
In this article, some complex parameters of the product and design processes, how to match and optimise the sub-parts of related industrial products and how to improve the quality of the corresponding products and the competitiveness of the product in the international market are discussed in this article. We also build an algorithm based on the particle swarm and XGBoost algorithms, combined with the intelligent computing of the Internet of Things (IoT). We transform some uncertain factors in the process of the industrial product design process through the fuzzy matrix, select the optimal design through the optimised intelligent computing of the IoT scheme and compare the influence of the scheme before and after optimisation on production efficiency. The results show that the method proposed in this article can reduce the time-consumption of optimal solution selection by 42.85%–52.94%. In addition, selecting the optimal solution for each field in a targeted manner can increase the overall production efficiency of the product by about 5%, reaching between 93.6% and 96.5%, which may save raw materials and create more economic value.
De Bruijn sequence is an important kind of nonlinear shift register sequence, which has a very wide range of applications in the fields of communication and cryptography. From the perspective of the relationship between linear terms, quadratic terms and cubic terms in the feedback functions of de Bruijn sequences, some new necessary conditions for feedback functions of de Bruijn sequences are obtained. Some examples show that the known necessary conditions cannot deduce the proposed necessary conditions.
With the development of history, some folk dances are annihilated and lost in the inheritance. In order to protect and inherit national intangible cultural heritage and promote the construction of advanced socialist culture, this paper uses information fusion technology, combines national aesthetic personality, and refers to multi-factor theory, construction theory, and distillation theory to design and reform the art practice model of folk dance education. The data of dancers’ skeletal joint points are collected by using multiple Kinect sensors, and the Kalman filter algorithm is selected to establish the human skeletal motion model and fuse the data information of each joint point. Taking the hand_right and elbow_right joints as examples, it was found that the mean value of the error between the testers’ joint trajectory and the template movement was reduced from 10mm to 4mm, and the mean value of the error between the joint angle and the template movement was reduced from 90° to 35°. Comparing the dance movement training effects and scores of the experimental group and the control group, it was found that the experimental group kicked the front and side legs an average of 70 times/minute, the middle jump height was improved by 10cm, and the average score was 3.33 points higher. This indicates that the integration of information fusion technology in the art practice of dance education can realize the practical innovation of college folk dance education and improve the comprehensive level of folk dance.
The study uses a modified Kalman filter to analyse the impact of innovative human capital’s contribution to China’s economic development. The Kalman filter-STI model is used, and the growth rates of labour force, physical capital and innovative human capital and their contributions to economic growth are further calculated. The analysis employing the Kalman filter-STI model leads to the following results: In 2015, the sum of innovative human capital in each region increased by 6.15% compared to 2010. From 2005 to 2021, the number of scientific and technical papers included in three international systems in China decreased from 45% to 31% in Beijing, from 34% to 21% in Shanghai, and decreased in Jilin and Gansu. Jiangsu Province is the province with the largest increase in the share, from 13% to 26%.
Internet technology is developing rapidly, and young students, as the subjects of Internet use, are also the objects of college civic education. Based on the Internet+ era, the strategy of integrating traditional culture with the path of college Civic Education has become a necessary issue for reforming this educational direction and the purpose of this paper. Based on the information and culture dissemination mode of the Internet, this paper integrates traditional culture in exploring the path of Civic Education and puts forward an innovative method of college Civic Education. Compared with the original Civic Education method, the average satisfaction of students has increased by 6.6 percentage points, and the comparison has improved by 9.91%. The average satisfaction of teachers increased by 7.6 percentage points and by 9.84% in comparison. The percentage of students who think that the effect of Civic Education is very obvious has increased by 2.7%, the ratio of those who think it is improved has increased by 3.5%, the ratio of those who think it is generally improved has increased by 1.4%, and the ratio of those who think it has almost no improvement effect has decreased by 6.3 percentage points compared to the original. Traditional culture and Civic Education are organically integrated with the support of Internet technology, which optimizes the path of education realization, makes the path play the main role of students, strengthens the interaction in teaching, and refreshes the level of this educational work comprehensively.
The application of fractional partial differential equations (FPDEs) in college taekwondo has attracted more and more attention. Different FPDEs models have been applied to more and more fields, including: Materials, mechanics, and biological systems, and found that FPDEs have more advantages than integer order equation models in studying some materials with memory processes, genetic properties, and heterogeneous materials. The progress of FPDEs in university taekwondo has aroused people's interest in studying numerical algorithms. At present, the management of cardiovascular disease is mainly focused on rescue, drug treatment and revascularization at the onset of the disease, while less attention is paid to the prevention and prognosis management after treatment, leading to the increase of repeated diseases, readmission rate and mortality of patients. With the upsurge of heart rehabilitation dominated by exercise prescriptions, scientific aerobic exercise has gained more and more benefits. After 24 weeks of taekwondo intervention training, the author found that taekwondo exercise had a positive impact on its heart rate variability parameters (mean heart rate, RMSSD, LFnorm, HFnorm, HF), suggesting that taekwondo exercise may improve myocardial blood supply by regulating autonomic nerves. In addition, the Mate analysis of the effect of heart rehabilitation based on taekwondo on patients with coronary heart disease shows that taekwondo has a significant role in improving the aerobic endurance and mental health of patients with coronary heart disease.
With the continuous progress of society and the development of economy, the packaging design has also become a fierce competition for eye-catching products and because of the situation of more and more fierce competition of similar products, it prompted more and more designers to start a new Examining of their own national traditional ink art, which hope to absorb nutrients from traditional cultural elements, so as to enhance the cultural connotation and unique personality of the product, and this traditional ink art is the emotion with a long history accumulated in the hearts of the public. It has guided the public's lifestyle and aesthetic trends for a long time. The inheritance and transcendence of traditional ink art has become the only way to explore and develop national characteristic packaging design. Starting from the processing of ink image primitives, this paper analyses the pixel colour segmentation algorithm of ink image, extracts various elements and length and width parameters of ink image for line rendering based on packaging design, and calculates the vectorisation of ink image through bilinear difference algorithm. The latter design parameters are used to highlight the artistic design effect of the ink-wash style packaging.
In recent years, influenced by the deepening reform of colleges teaching English in China, teaching English for college students has gradually been favoured and promoted. At present, many universities still use traditional English teaching methods. The traditional English teaching method only allows college students to learn basic grammar and vocabulary, without the ability of independent learning. Given these problems, this paper first proposes a framework for cultivating college students’ autonomous learning ability in English teaching based on output-based education (OBE) theory. Then, the OBE theory is introduced in detail. At the same time, the framework is applied in a university. After a semester of study, the results are combined with teachers’ and college students’ questionnaire surveys. Finally, after the questionnaire results and analysis, the framework proposed in this paper is better than other traditional English teaching methods. The experiment also shows that it not only improves the adaptability of college students’ English teaching but also improves their independent learning ability while learning English.
This paper explores the pros and cons of different algorithm models on the same selection problem, and then uses the combined prediction theory to obtain a new combined prediction model to explore its prediction accuracy. The actual problem to be solved is to help financial institutions to scientifically classify customers who choose financial products. We select the bank data set in the UCI database, which is derived from the survey data of a customer conducted by a financial institution in Portugal for a wealth management product. Decision tree C5.0 algorithm, naive Bayes classification algorithm and binary logit model are individually used to carry out a single model of empirical research on financial product customer classification. Through the empirical analysis of the five combination models, it is concluded that in the model that uses the least squares weighting method to determine the weight, the weight appears negative, which does not conform to the actual situation. The model that is based on the least squares weighting method and the model that is based on the simple weighting method are excluded. In contrast, the arithmetic mean weighted model is better than the reciprocal variance weighted model and the reciprocal mean square model. The accuracy reaches 89.91%, which is 0.43% higher than the accuracy of a single model. It can be concluded that the model that is based on the arithmetic average weighting is a better combination forecasting model.
With the increasing role of knowledge and technology in the economy, human capital has become the decisive factor for economic development and social progress. Measuring, evaluating or predicting the level of regional human capital within a country can grasp the investment policy of human capital as a whole. Therefore, in this paper, a prediction model of regional human capital level based on optimised BP neural network is built. First, the evaluation system of the regional human capital is constructed by selecting 15 evaluation indexes in 5 categories, such as educational training, development of science and technology, medical care, labour migration and social security. Then, the PSO algorithm is used to optimise the BP neural network, and the core problems in the optimisation process are solved. Finally, the model is tested and analysed by the MATLAB simulation platform. The results show that the prediction accuracy of the model is high, and the output results are basically consistent with the reality, which is conducive to promoting the structural upgrading of human capital.

We obtain the joint angles of each stage of the shot throw through experimental design, time-consuming, final speed, limb displacement, shot-put shot speed, height, angle, and other kinematic parameters, and the shot-put motion trajectory of the picture stroke of the relevant action characteristics.
Colleges and universities are the major sources of scientific research. They reveal how the effectiveness is related to the development of the whole society and the living standards of all employees. This article starts from the education model, based on relevant theoretical knowledge. It helps to explore and innovate the path to realize the ‘college scientific research and teaching collaborative education model’ within the university and construct the SVM-process reengineering model to study its feasibility. According to the calculation results, the teaching results of the enterprise teaching mode are the lowest, with an average proportion of about 32.74%, the average proportion of the teaching results of the traditional teaching mode is only 42.56%, and the average proportion of the teaching results of the collaborative education is as high as 97.86%. Therefore, measures should be taken to enhance the flexibility of training content and to carry out various forms of school research, teaching and collaborative education models.
Bounded rationality, asymmetric information and foreign trade are widespread in the economic market, and have been studied extensively in oligopoly games, but there are not many works discussing asymmetric information and bounded rationality in the supply chain hybrid game. In contrast with existing works, in our study, we innovatively construct a duopoly Bertrand–Cournot game model in a transnational supply chain with bounded rationality and asymmetric information. It is assumed that upstream firm 1 knows all the market information and adopts boundedly rational expectation, while downstream firm 2 only partially knows the market information and uses naïve expectation. Based on game theory and nonlinear dynamic theory, the complexity of the discrete system is analysed with respect to effective information, shareholding ratio and price sensitivity. Results reveal the following: (i) When the downstream firm knows little about the price information of the upstream firm, the market may be unstable or even chaotic; otherwise, it is conducive to the stability of the product market. (ii) When the shareholding ratio or the price sensitivity is relatively small, the market is more stable, and as they increase, the discrete price-production system goes through bifurcation and eventually falls into chaos. Our research has an important theoretical and practical significance for price-production supply chain competition in oligopoly markets.
Under the wind load, a structure produces the vortex vibration effect, which threatens the safety and durability of a bridge. Because of its low wind speed and high frequency, it poses a serious safety hazard to safety in the construction state and the traffic safety in the completed state. Therefore, in this paper, a numerical simulation method of vortex-introduced vibration (VIV) performance in the main girder of cable-stayed bridge based on bidirectional fluid-solid coupling is proposed. Taking CFD control equation as the constraint condition, the main girder model is divided into the calculation domain, grid division and boundary condition setting using the Gambit pre-processing software, and a vortex-induced force (VIF) model of the main girder based on the simulation process is proposed. Finally, based on the parameters of the main girder section model, the numerical simulation results of the vortex vibration performance of the main girder are analysed, and the results show that the vortex vibration test results are basically consistent.
There are 94 countries and regions along the Belt and Road (CRBR). China proposed the Belt and Road Initiative (BRI) in 2013, and it encompasses five core elements: unimpeded trade (UT), policy coordination (PC), infrastructure connectivity (IC), financial integration (FI) and people-to-people bond (PPB). The BRI has facilitated international relations and multilateral trade, in addition to building a community with a shared future for mankind. However, factors such as political relations and cultural distance have affected bilateral trade (BT) between China and CRBR. Further analysis is required to explore the association between UT and policy, infrastructure, financial and people-to-people connectivity. A multiple linear regression analysis using SPSS 20 revealed that: (1) IC, FI, PPB and improved economic levels can promote BT to varying degrees, but spatial distance inhibits the development of BT; and (2) the coordination between policy subjects does not promote UT up to any significant level. Accordingly, strengthening infrastructure and FI, promoting people-to-people and bilateral exchanges, and opening extra China–Europe freight trains and maritime transport will enhance UT, expand BT and invigorate the global economy.

The marketing strategy of national fitness exercise and dance events is a brand new marketing model built on big data technology and modern sports marketing theory. With the development of big data Internet technology, national fitness exercise and dance event marketing will certainly bring a positive impact on the audience and promotion channels of fitness exercise events. The scope of participation expands year by year, the number of participants expands year by year, the number of participants rises year by year, etc., thus promoting the healthy and rapid development of national fitness exercise and dance event marketing and sports culture construction plays a positive role.
Analyzing the economic benefits of enterprise employees is better for protecting the rights and interests of enterprise employees. In this paper, based on the K-means clustering algorithm in the context of the Internet, the K-means clustering algorithm is optimized by the entropy weight method, and a K-means clustering model for exploring the analysis of the economic benefits of enterprise employees’ labor is proposed. For the model of this paper, the classification accuracy of the model is verified by employing controlled experiments, and two types of evaluation indexes for the labor economic efficiency of enterprise employees are analyzed and mined, namely labor employment and work environment and wage compensation and training and learning, using enterprise T as an example. Regarding labor and work environment indicators, 74.52% of the evaluations were above C grade. From the data of the indicators of salary and compensation and training and learning, the percentage of C grades or above is 89.41%. In the background of the Internet, the K-means algorithm model to analyze the relationship between the economic benefits of enterprise employee labor can help enterprises understand the current problems of employee labor and improve the happiness of employee labor, thus promoting the increase of enterprise economic benefits.

A good 3D animation, it requires producers to have a better sense of space and artistic sense, there is must be a good use of all kinds of 3D animation production software. The image design of animated characters from the perspective of content, design styles and styles vary greatly from reality to non-reality. However, whether taken from nature or elsewhere, they are inseparable from their character as a vehicle for expressing human spirit and emotion. Since the birth of animation, its prominent entertainment function has become the value of the existence of this art style, and it has the possibility of development. And animated characters are more iconic than any other element of animation. The purpose of animation character design is to give appeal and vitality to each animation character art.

Graphene is a new type of two-dimensional carbon material with excellent mechanical strength, high thermal conductivity, high light transmittance and high specific surface area. Its excellent performance makes it suitable for high-performance electronic devices, composite materials, gas sensors and energy storage and other fields, and has broad application prospects, especially its ultra-high thermal conductivity has attracted great interest of scholars at home and abroad. In this study, the heat transfer theory and the heat transfer mechanism of graphene are firstly cited, and three commonly used composite heat transfer fitting models are proposed. Advantages and disadvantages of measurement methods are described. According to the aforementioned theoretical basis, the equilibrium molecular dynamics and non-equilibrium molecular dynamics heat transfer models were used to fit graphene and its composites, and the thermal conductivity of graphene composites was analysed. Finally, the future research directions of graphene thermal conductivity are prospected.
LOT wireless sensor nodes are limited by physical factors, usually have weak computing power and endurance, and wireless communication methods are very vulnerable to information theft. Therefore, it is of great significance to ensure the safe and efficient transmission of images in new application scenarios. In view of the need for an efficient image transmission, this paper combines compressed sensing technology with p-tensor product theory, applies the above theory to distributed wireless sensor networks, and uses the correlation of adjacent sensor nodes in wireless sensor networks to propose an improved a joint sparse model for measurement matrices and reduction algorithms. The feasibility is verified by simulation experiments, and the comparison between joint reconstruction and single reconstruction, and the application of various algorithms in other algorithms is carried out, and the actual completion time and storage capacity are analysed. The minimum completion time for wavelet transform is 1.29, the sparse estimated time for the selection of preliminary P waves is 0.07 and the compressed sensing time is 0.20. The maximum completion time for wavelet transform was 1.32, for sparse estimation, it is 0.62, for preliminary P-wave selection, it is 0.17, and for compressed sensing, it is 0.88. The processing time is no >3 s and the runtime is only 0.22–0.88 s. The results show that compared with the compressed sensing of a single node, the joint sparse model based on distributed compressed sensing has a smaller reconstruction error, and can achieve high-precision signal reconstruction when the measurement value is small.
Distribution network planning is an important task in the process of power grid construction and development. Scientific and rational planning is the key factor for the economic construction and reliable operation of the power grid. Aiming at the difficulty in quantifying the weight of distribution network planning schemes, a comprehensive evaluation method of distribution network planning schemes based on the interval-valued intuitionistic fuzzy analytic hierarchy process method is proposed. First, a comprehensive evaluation index system is established from the four aspects of power supply, namely reliability, economy, power supply quality and safety of the distribution network. Then, a comprehensive evaluation method of electricity reliability optimised by entropy weight method is adopted by analytic hierarchy process, which considers both subjective situation and objective weighting. At the same time, the comprehensive weight of the aggregation of the criterion layer and the scheme layer is calculated. Finally, the link between the aggregation matrix and the index weights of the criterion layer is used to calculate the weights of the scheme layer so that they can be sorted out. The experimental results show that the effectiveness and feasibility of the planning and analysis indicators and evaluation methods of the method proposed in this paper are verified by a numerical example.
