基于高冲突修正的D-S证据融合方法
D-S Evidence Fusion Method Based on High Conflict Correction
摘要
Abstract
Before using D-S(Dempster-Shafer) theory for evidence fusion,the extent of the conflict among evidences should be determined.Aiming at this problem,this paper proposes a conflict measure and correction method based on trust degree and false degree.It calculates both trust degree and false degree of each evidence and sorts them respectively.The evidence with smaller trust degree and larger false degree is called high conflict evidence and done weighted correction.Then the Dempster combination rule is used for evidence fusion.Experiment results show that the proposed method can correctly judge the high conflict evidence and solve the problem that the fusion result contradicts the fact,while improving the speed and precision of convergence.关键词
