Similarity Measure and Fuzzy Entropy of Fuzzy Number Intuitionistic Fuzzy Sets

摘要

Based on the similarity measure of trigonometric fuzzy numbers, similarity measures for measuring the degree of similarity between elements and between some fuzzy number intuitionistic fuzzy sets are denned by the one-to-one correspondence relation between the distance and similarity measure. At the same time, the fuzzy entropy for fuzzy number intuitionistic fuzzy sets is proposed. After that, their properties are discussed and an example about the application of similarity measure to pattern recognitions is given.
