Abstract

Based on the cluster width of probability density functions (WCD), we establish algorithms for fuzzy cluster analysis and for determining the suitable number of cluster. In addition, determining WCD for two and more than two probability density functions has been also considered by our Matlab produces. The numerical examples in both synthetic and real data are given not only to illustrate the reasonable of proposed algorithms and programs but also to show their advantages in comparing with existing ones.
Keywords: Clustering, density, distance, fuzzy, width
