Evidence combination based on the degree of credibility and falsity by ONGYa-fei S, ANGXiao-dan W, EILei L, UEAi-jun X

“…D-S evidence theory has been widely used in various fields of information fusion due to its efficiency in deal-ing with uncertain information.Unfortunately,combination of conflicting evidences by classical Dempster's rule may produce counter-intuitive results.To alleviate this problem,a new weighted average combination rule is proposed.Defi-nitions of correlation coefficient was first presented,followed by the introduction of falsity.Then the credibility of evi-dence is proposed.A new weighted coefficient is determined by credibility and falsity.To achieve convergence,the nor-malized weighted coefficient was suggested into the Dempster's combination rule to average the basic probability as-signment.Comparable numerical examples demonstrate that the proposed approach can combine conflicting evidences more effectively.Moreover,the proposed methodology can provide a faster identification of the observed object.…”

Fault diagnosis method based on time domain weighted data aggregation and information fusion by Yu Zhang, Wen Jiang, Xinyang Deng

“…At last, the basic probability assignments generated under each fault feature are fused by Dempster combination rule. The proposed method is verified and the results show that the total fault recognition rate can reach 97.5%, which increased by 1.9% compared with the method that Gaussian model constructed by original data.…”
