Hierarchical clustering pdf
WebA hierarchical clustering method generates a sequence of partitions of data objects. It proceeds successively by either merging smaller clusters into larger ones, or by splitting larger clusters. The result of the algorithm is a tree of clusters, called dendrogram (see Fig. 1), which shows how the clusters are related.By cutting the dendrogram at a desired … WebWard's Hierarchical Clustering Method: Clustering Criterion and ...
