COSINE SIMILARITY AND ITS APPLICATION BY PYTHAGOREAN FUZZY SETS

ABSTRACT

A Pythagorean fuzzy set is the successful ?eld which includes membership and non membership functions. It has been extended from intuitionistic fuzzy set. It reaches many application with the support of score, Accuracy, Distance and Similarity measures. In this paper, cosine similarity measure is used with Pythagorean fuzzy set. An algorithm is developed for proposed method. An illustrative example is included. Comparison is also made with Score, Accuracy and Similarity measure function.
