A High-Conflict Evidence Fusion Method Based on Average Evidence and Focal Element Distance
The classical DS evidence theory cannot effectively conduct high-conflict evidence fusion.To solve the problem, a high-conflict evidence fusion method based on average evidence and focal element distance is proposed.Firstly, Pearson correlation coefficient is used to calculate the correlation between evidence bodies, and the weight of evidence is defined to calculate the average evidence.Then, the average evidence is used to calculate the focal distance of each evidence element, and the conflict is redistributed to each focal element BPA according to the focal distance to construct a new evidence body.Finally, the traditional Dempster combination of the new evidence body is conducted to obtain the fusion result.Simulation experiments show that the new method has high accuracy and fast convergence rate when dealing with high-conflict evidence, which provides a good solution to the problem of high-conflict evidence fusion.
