Abstract

Recently Dengfeng and Chuntian defined the first operational definition of a similarity measure for intuitionistic fuzzy sets and showed how it may be used in pattern recognition problems. Unfortunately the Dengfeng and Chuntian operator may give counter-intuitive results. We show how a simple modification of the Dengfeng-Chuntian operator may correct this problem. We illustrate the application of the modified similarity measure on a simple pattern recognition problem.
