COSINE SIMILARITY AND ITS APPLICATION BY PYTHAGOREAN FUZZY SETS

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.

Oral leukoplakia: Management protocol for primary health-care providers and family physicians

Oral cancer is very common in India. Most of the oral cancers develop on a potentially malignant (precancerous) lesion. Leukoplakia is the most common precancerous lesion in the oral cavity.
