A modified evidence combination approach based on ambiguity measure

Dempster rule of combination is an effective method in evidence reasoning; however, the original combination rule may produce counterintuitive results when there are severe conflicts among evidences due to the discarding of contradictory mass assignments. In this paper a modified combination rule is proposed based on ambiguity measure (AM), which can describe the evidencepsilas degree of uncertainty. Weight factors are generated based on the AM of evidences to reallocate conflicting mass assignments. The combination results based on the proposed approach can be more reasonable. Experiments and examples provided show the efficacy and validity of the proposed approach. Comparisons with other modified evidence combination rules are also provided.
