A new effective soft clustering method. Sectional set fuzzy C-means (S2FCM) clustering

A new effective soft clustering method-sectional set fuzzy C-means (S2FCM) clustering is presented, in which the ideas of traditional "hard" clustering (HCM) and "fuzzy" clustering (FCM) are united and generalized. A effective /spl lambda/ value (/spl lambda//spl isin/~0,1\ is a factor of fuzzy sectional set) of S2FCM is /spl lambda/=0.5+1/2c (c is the total number of clusters). The main idea of the proposed method accords with procedure of a human's partition process in pattern recognition. Experimental results show S2FCM clustering method's effectiveness and advantage.
