General framework for evidence combination and its approach to highly conflicting evidence fusion
Zheng Qin · Journal of Tsinghua University(Science and Technology) · 2011
Counterintuitive and invalid conclusions are produced by the D-S theory of evidence with highly conflicting evidence.This paper gives a principle for effective problem solving when both evidence sources and combination rules have to be improved together,with a general framework for evidence fusion.First,two-level reliability measurements are applied to deal with evidence sources.After that,the improved evidence sources are fused by the combination rules.Finally,the conflicting coefficient is apportioned to focal elements based on the weights calculated from the Pignistic probability distance,which gives reasonable corrections for the fused results.Tests demonstrate that the approach more effectively settles the problem caused by highly conflicting evidence fusion than other methods.
