冲突证据融合方法的研究与改进

研究了D-S证据理论组合冲突证据时存在的缺陷,分析了国内外专家学者的研究成果,并在此基础上提出了一种改进的处理冲突证据的融合方法.该方法通过计算各证据到命题平均支持度的偏差来检测和融合冲突证据,并对最后结果进行了必要的修正,以解决来自不同识别框架的证据的合成问题.实验结果表明,该方法能有效处理冲突,得到符合实际的组合结果,相对于其它典型算法,该方法在收敛性和可靠性上有了明显改进.

Research and improvement of fusion approach for conflicting evidence in D-S evidence theory

The invalidation problem of D-S evidence theory in combining conflicting evidence is analyzed,and an improved method dealing with the fusion of conflicting evidence based on previous research is proposed.The method detects and eliminates the conflicting evidence by calculating the deviation from all evidence to the average support-level for the proposition.And it also amends the end result to handle the combination of evidence from different recognition framework.The numerical experiment shows that accurate...
