Similarity Measures between Temporal Complex Intuitionistic Fuzzy Sets and Application in Pattern Recognition and Medical Diagnosis

Abstract EN

This work addresses the issue of similarity measures between two temporal complex Atanassov’s intuitionistic fuzzy sets, many measures of similarity between complex Atanassov’s intuitionistic fuzzy sets.

What was proposed before did not consider the abstention group influence, which may lead to counterintuitive results in some cases.

A new structure of temporal complex Atanassov’s intuitionistic fuzzy sets is obtained.

This set is formally generalized from a conventional Atanassov’s intuitionistic complex fuzzy sets.

Here we analyze the limitations of the existing similarity measures.

Then, a new similarity measure of temporal complex Atanassov’s intuitionistic fuzzy sets is proposed and several numeric examples are given to demonstrate the validity of the proposed measure.

Finally, the proposed similarity measure is applied to pattern recognition and medical diagnosis.
