一种新的基于证据权重的D-S改进算法
A New Improved D-S Algorithm Based on Weight of Evidence
摘要
Abstract
Dempster-Shafer evidence theory is an effective method for dealing with uncertainty problems,but the results obtained are counterintuitive when the evidences highly conflict with each other. According to the importance of the evidences,a new improved D-S algorithm based on the weight of evidence is presented to solve this problem. Firstly,a distance function between the bodies of evidences is introduced,the average Euclidean distance between evidence and evidence subset is obtained after establishing the evidence distance matrix,and then modify the evidence through the belief function to get weight coefficients which describe the importance degree of evi-dence,finally these modified evidences are combined together according to the D-S rule. Through the numerical study and compared with the other improved methods verify the validity and superiority of the new method.关键词
