An Improved Universal Evidence Combination Method

The Dempster-Shafer evidence combination method will appear inconsistent conclusions for the conflict evidence. One new universal evidence combination method was proposed. According to the concept of the Pearson correlation coefficient. Evidence distances which represent the conflict degree were calculated, and then the weight coefficient were further converted. The evidences probability were redistributed by using the weight coefficient. Finally, the improved synthesis rule was used to the evidence combination. The examples results show that the algorithm has strong versatility and stability in the evidences combination, can be applied to information fusion, uncertain information decision-making and other fields.
