data mining , etc., very many different methods were developed in several communities. Detailed surveys of this domain can be found in [25], [27] or [26]. In the following, we attempt to briefly review a few core concepts of cluster analysis and describe categories of clustering machine learning, pattern recognition, and scientific, engineering, social, economic, and biomedical data analysis . Although there have been numerous studies on clustering methods and their applications con- sidering the surge of research activities on cluster analysis in the
