Abstract	摘要:该文对 Dempster-Shafer(DS)理论以及 Dezert-Smarandache 理论(DSmT)进行了深入研究,为了能够在仅需较低计算复杂度的前提下得到更加精确的融合结果,提出一种新的快速 DSmT-DS 近似推理融合方法。该方法针对超幂集空间仅单子焦元具有信度赋值的情况,将超幂集空间拆分映射成元素为各单子焦元和其补集的二元集合的新的超幂集空间,并求出每个补集的信度赋值;再运用 Dezert-Smarandache 框架中的第 5 条比例冲突分配规则 (DSmT+PCR5)在新的超幂集空间的二元集合子空间下对多证据源进行融合,得到各单子焦元的融合结果;然后通过归一化处理求得各单子焦元的信度赋值。通过理论分析得出该文方法的融合结果是介于 Dezert-Smarandache 框架中的第 5 条比例冲突分配规则(DSmT+PCR5)及 Dempster-Shafer(DS)框架下的 Dempster 组合规则之间。该文方法在需要较低计算复杂度的前提下,可以得到优于 Dempster 组合规则的近似融合结果。最后通过多个角度与已有方法进行对比,验证了该文方法的优越性。关键词:信息融合;证据理论;Dezert-Smarandache 理论;近似推理;拆分映射中图分类号: TP391 文献标识码: A 文章编号:1009-5896(2015)09-2040-07 DOI: 10.11999/JEIT150086
