Fermatean fuzzy sets and their variants
Fermatean fuzzy modified composite relation and its application in pattern recognition

Paul Augustine Ejegwa; Doonen Zuakwagh

Volume 3, Issue 2 , June 2022, , Pages 140-151


  Fermatean Fuzzy Sets (FFSs) provide an effective way to handle uncertainty and vagueness by expanding the scope of membership and Non-Membership Degrees (NMDs) of Intuitionistic Fuzzy Set (IFS) and Pythagorean Fuzzy Set (PFS), respectively. FFS handles uncertain information more easily in the process ...  Read More

Intuitionistic fuzzy sets and their variants
Medical diagnostic analysis on some selected patients based on modified Thao et al.’s correlation coefficient of intuitionistic fuzzy sets via an algorithmic approach

Paul Augustine Ejegwa; Idoko Charles Onyeke

Volume 1, Issue 2 , June 2020, , Pages 122-132


  The concept of correlation coefficient of intuitionistic fuzzy sets is a reliable tool in information theory with numerous applications in diverse areas. Correlation coefficients of intuitionistic fuzzy sets have been studied through two-way approach by many researchers. This approach inappropriately ...  Read More
