A fuzzy modeling approach to cluster validity

Abstract: Abstract-This paper presents a new approach to find the optimal number of clusters of a fuzzy partition. It is based on a fuzzy modeling approach which combines measures of clusters' separation and overlap. Theses measures are based on triangular norms and a discrete Sugeno integral. Results on artificial and real data sets prove its efficiency compared to indexes from the literature.

“…Almost all mentioned methods only based on distortion information from within clusters. Hoel Le Capitaine and Carl Frélicot [5] introduce an approach to find the optimal number of clusters of a fuzzy partition. They use measures of separation and degree of overlap of the clusters based on triangular norms and a discrete Sugeno integral.…”
