摘要/Abstract

摘要：

为了能够减小基于Dezert-Smarandache理论(DSmT)框架的第5条比例冲突分配规则(PCR5)处理含有交多子焦元证据融合问题的计算复杂度并保持较高的精度,本文提出一种多子焦元信度赋值非零情况下的DSmT近似融合推理方法.该方法避免了现有的基于Shafer模型的DSmT近似融合推理方法由于需要预先解耦带来的信息损失,并且不仅适用于Shafer模型也适用于混合Dezert-Smarandache(DSm)模型下部分交多子焦元非冲突且信度赋值非零的情况.仿真实验表明,在不同的情况下,本文方法相比现有的方法,与DSmT+PCR5融合推理方法融合结果相似度更高且计算效率显著提高.

Abstract:

For reducing the computation complexity of the Proportional Conflict Redistribution No.5 (PCR5) with the framework of Dezert-Smarandache Theory (DSmT) for evidence fusion problems of mulitple focal elements and remaining high accuracy, a Dezert-Smarandache Theory (DSmT) approximate reasoning method on the condition of non-zero mulitple focal elements is proposed.The method avoids the informaiton loss caused by decoupling of the existed DSmT approximate reasoning method.The information fusion problems of non-zero mulitple focal elements based on not only the Shafer model but the hybrid-Dezert-Smarandache (DSm) model can be effectively processed by the proposed method.Finally, simulation results show that in different conditions, the proposed method can get more similar results with DSmT+PCR5 method and need less computation complexity compared to the existed method.

Key words: evidence theory, approximate reasoning, information fusion, hybrid-DSm(Dezert-Smarandache) model, dezert-smarandache theory
