Directional correlation coefficient measures for Pythagorean fuzzy sets: their applications to medical diagnosis and cluster analysis

نویسندگان

چکیده

Abstract Compared to the intuitionistic fuzzy sets, Pythagorean sets (PFSs) can provide decision makers with more freedom express their evaluation information. There exist some research results on correlation coefficient between PFSs, but sometimes they fail deal problems of disease diagnosis and cluster analysis. To tackle drawbacks existing coefficients novel directional are put forward compute relationship two PFSs by taking four parameters into consideration, which membership degree, non-membership strength commitment, direction commitment. Afterwards, practical examples given show application proposed in diagnosis, weighted Finally, compared previous that have been developed for PFSs.

SOME SIMILARITY MEASURES FOR PICTURE FUZZY SETS AND THEIR APPLICATIONS

In this work, we shall present some novel process to measure the similarity between picture fuzzy sets. Firstly, we adopt the concept of intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets and picture fuzzy sets. Secondly, we develop some similarity measures between picture fuzzy sets, such as, cosine similarity measure, weighted cosine similarity measure, set-theoretic similar...

Correlation coefficient of intuitionistic fuzzy sets

Based on the point of view of geometrical representation of an intuitionistic fuzzy set, we take into account all three parameters describing intuitionistic fuzzy set, propose a kind of new method to calculate correlation and correlation coefficient of intuitionistic fuzzy sets which is similar to the cosine of the intersectional angle in finite sets and probability space, respectively. Further...

Utility of Correlation Measures for Weighted Hesitant Fuzzy Sets in Medical Diagnosis Problems

Due to importance of correlation measure in data analysis, some researchers have shown great interest in the concept of correlation measure for extensions of fuzzy sets, in particular, for a new extension known as hesitant fuzzy set (HFS). Recently, an extension of HFS called the weighted hesitant fuzzy set (WHFS) has been developed by Zhang and Wu [1] to allow the membership of a given element...
