The Application of Similarity Measures Between Vague Sets in Evidence Theory
Huang Yime · Journal of University of Jinan · 2014
Evidence combination rule plays an important role in Dempster-Shafer( DS) evidence theory. However,the Dempster combination result could not identify the actual conditions when faced with seriously conflicting evidence. A better solution is to pretreat the evidence before combination,namely evidence weighted average. After studying the relationship between DS evidence theory and Vague sets,the similarity measurement between different Vague sets is applied to evidence combination. By comparing the combining results,we find that the similarity measurement between Vague sets and the modified DS evidence combination has similar effect in object recognition and convergence,indicating that some useful conclusions of Vague set theory can be applied to the evidence theory, which will be helpful in handling and studying the uncertainty of knowledge.
