Abstract :
Based on a framework, that casts the problem of clustering a set of data points as a problem of clustering the associated pairwise distances, this study generalizes the silhouette measure to fuzzy partitions, in turn, proposing an outstanding tool to the validation of crisp and fuzzy clustering results.
