基于信度函数的冲突证据组合新方法

为了有效地处理冲突证据，提出了一种基于信度函数的新方法．设计了一个证据信度函数，并用此函数来计算证据之间的后验权重分配．给出了先验权重和后验权重的合成方法，从而得到最终权重分配．采用最终权重对现有证据进行加权平均，并采用Dempster—shafer组合规则进行融合，从而得到最终融合结果．与其他方法相比，该方法考虑的因素更全面、适用性更强．实例表明，该方法能够比其他方法更快、更有效地识别出目标．

New combination approach based on creditability function for conflict evidences

In order to efficiently combine conflict evidences, a new creditability function method was For getting the evidence-based weight distribution, an evidence creditability function was introduced to estimate the weight distribution of the bodies of evidence. Then, the final weight distribution got through the composed method proposed for combining the weights of foregone and evidencebased. Finally,weightedly averaging the existing evidences, the Dempster-shafer combination rule was used to realize information fusion. Comparing with other approaches, the approach above mentioned considers more factors and has stronger practicability. It can be found from examples presented that the approach proposed can recognize the target faster and more efficiently than others.
