一种新的基于证据距离的证据合成算法
New Evidence Composition Algorithm Based on Evidence Distance
摘要
Abstract
Since Dempster-Shafer (DS) theory involves counter-intuitive behaviors when evidences highly conflict, a new approach of combination of weighted belief functions based on evidence distance is proposed. The new approach still uses DS combination formula, but considers the revision means which fuses the evidence source of the system. Jousselme evidence distance is revised by making use of expectation of all evidences, and then obtains the evidence weight. The basic beliability partition function of source evidence is revised through evidence weight. The numerical examples are given to illustrate the effectiveness and the good performance of the new approach in case of high conflict between evidences.关键词
