A Note on 'New Estimation Method for the Membership Values in Fuzzy Sets'

摘要

Chen et al. [1], have proposed a new estimation method for the membership values in fuzzy sets. The proposed scheme takes input from empirical/experimental data, which re- flect the expert's knowledge on the relative degree of belonging of the members, and then searches for the best fit membership values of the element. Through the estimation of the practical case (Sect. 3 in [1]) the algorithm suggests to normalize the esti- mated membership values if there is any among them more than one and change some condition to guarantee its positiveness.
