Validity index for crisp and fuzzy clusters

TLDR
A cluster validity index and its fuzzification is described, which can provide a measure of goodness of clustering on different partitions of a data set, and results demonstrating the superiority of the PBM-index in appropriately determining the number of clusters are provided.

A point symmetry-based clonal selection clustering algorithm and its application in image compression

TL;DR: An immune vaccine operator is introduced to the classical clonal selection algorithm, which can gain a priori knowledge of pending problems so as to accelerate the convergent speed and a point symmetry-based similarity measure is used to evaluate the similarity between two samples.
