The overlapping nature of clusters is better expressed in fuzzy clustering [11],[12] and [13]. The popular algorithms include fuzzy c-means (FCM) [14] and fuzzy c-shells algorithm (FCS) [15]. In this approach each element of a dataset belongs to all the clusters with a fuzzy membership grade. The fuzzy clustering can be converted to a crisp clustering (any element belongs to one cluster only) by assigning each element to the cluster with highest measure of membership value.
