International Journal of Engineering and Information Systems (IJEAIS)   Year: 2017 | Volume: 1 | Issue: 4 | Page No.: 28-37 Synchronized Clustering: A review on Systematic comparisons and Validation of prominent Block-clustering Algorithms Vittapu, Mani Sarma Abstract: One of the major problems in clustering is the need of specifying the optimal number of clusters in some clustering algorithms. Numerous indices were proposed in order to find reasonable number of clusters. The purpose of the paper is to test the performance and ability of some indices to detect the proper number of clusters on rows and columns partitions obtained by a block clustering algorithm. Simultaneous clustering methods perform clustering in the two dimensions simultaneously. The purpose of the paper is to test the performance and ability of some indices to detect the proper number of clusters on rows and columns partitions obtained by a block clustering algorithms .and also focus on a large number of existing simultaneous clustering approaches applied in text mining, web mining, information retrieval as well as bioinformatics and categorize them in accordance with the methods used to perform the clustering and the intention applications. The main goal of this paper is to provide a systematic comparison and validation of prominent bi-clustering algorithms.
