基于焦元识别置信度差异的证据组合

Combination rules of evidences based on various credibility of different focus discernment

由于多证据源各有擅长,即使同一证据源对于不同事件判定的置信度也各不同,使用传统Dempster-Shafer理论往往得到与直觉相悖的结果,因此使用不同的擅长因子衡量证据对不同焦点元素判定的置信度,并将其引进信任函数,所有的证据经过擅长评估后再进行组合,实验证明,给定方法比传统D-S理论提高了融合的准确性。

The wrong results are often got using traditional Dempster-Shafer rules due to the difference of credibility from multi-evidence. The evidence sources are adapted in different cases. The credibility of the evidence changes by the different focus element. So, in evidence, various credibility is given for evcry focus element. These parametersjoin in the belieffunction. Evidences are first estimated with these parameters and then combined. The conclusion is significant after the final experimental test comparing with traditional D-S theory.
