IMPROVING EFFICIENCY AND EFFECTIVENESS OF HIERARCHICAL CLUSTERING

P. Praveen, B. Rama

Abstract


Clustering techniques will formulate the edifice of the groups by divide the instances in whichever a bottom-up or top-down fashion. These methods are divided into Divisive hierarchical clustering and Agglomerative hierarchical clustering. The nested combining of objects and corollary levels at which groupings change will be represented by the corollary of these methods. The clustered items are achieved by wounding dendrogram at the desired likeness rank. Here the Single linkage method is inter dependent on correlation of two clusters that are nearest points in different clusters. Complete linkage method is reliant on the correlation of two clusters that are least similar points in the different clusters. Average linkage method is reliant on the average of pair wise closeness between the points in two clusters. For choosing which strategies are most appropriate for a given dataset, here we proposed a ensemble based system
