摘要：Clustering algorithms are one of the ways of extracting the valuable information apart from a large database by partitioning them. All of these clustering algorithms have their main goal that is to find clusters by maximizing the similarity in intra clusters and reducing the similarity between different clusters. Besides of their main goal, all of these algorithms work on different problem domain. In this paper, two algorithms Kmeans and spectral clustering algorithm are described. Both algorithm are tested and evaluated on different applications driven dataset. For calculating the efficiency of the clustering algorithm, silhouette index is used. Performance and accuracy of both the clustering algorithm are presented and compared by using validity index.
