Center-wise intra-inter silhouettes

Abstract

Silhouettes were defined as measures of clustering quality in the context of crisp partitions. This study extends the work that generalized silhouettes to fuzzy partitions in a natural profound manner. As opposed to constructing silhouettes for each data point, described here is the construction of silhouettes for each cluster center in terms of center-to-point distances rather than point-to-point distances. © 2012 Springer-Verlag.
