| 摘 要： | DS证据理论在决策级信息融合中有着广泛应用.针对证据组合时的某些反直观结果问题提出一种新的基于证据方差的序贯式加权证据组合方法.首先基于Jousselme证据距离定义了证据方差.每一步证据组合时,依据当前既有证据组合结果序列的方差及当前步新证据加入后的序列方差来生成权重.基于所获权重修正新到证据及前一步组合结果,最后利用Dempster规则完成当前步证据组合.算例分析表明所提方法是合理有效的.

| Abstract: | Dempster-Shafer evidence theory is widely used in the fields of decision-level information fusion.To suppress the counter-intuitive results encountered when using Dempster's rule of combination,a modified sequential weighted evidence combination approach based on variance of evidence is proposed.According to Jousselme's distance,variance of bodies of evidence is defined.In each combination step,the weights are generated based on the variances of the sequences of available evidence combination results before... |
