Abstract

The goal of this study is to evaluate the qualities of various clusters and their improvements using some techniques. A comparative analysis is carried to identify the quality cluster. Distance measures are presented for measuring the distance functions. The selection of centroids, influence function, density function, pseudo inverse and other related concepts are mathematically explained for utilizing in this work. Density and entropy expressions are provided to exhibit the quality clusters. For the purpose of discussing the quality of various clusters the densities, entropies and weights relating to S, SA and W clusters are computed. The improvement of cluster quality based on above concepts have been analysed. A comparison is made among S, SA and W clusters and pointed out the quality clusters.
