Clustering is a process of extracting reliable, unique, effective and comprehensible patterns from database. Various clustering methods are proposed to accomplish exactness and accuracy of clusters. K-means is well known clustering algorithm but it easily converge to local optima. To overcome this drawback, an improved algorithm called K-Harmonic Mean (KHM) was proposed, which is independent of cluster center initialization. This paper presents study of hybridization KHM with other clustering algorithms. In order to improve the clustering accuracy the authors proposed new hybrid KHM model.
