WebIntroduction to Hierarchical Clustering. Hierarchical clustering is defined as an unsupervised learning method that separates the data into different groups based upon the similarity measures, defined as clusters, to form the hierarchy; this clustering is divided as Agglomerative clustering and Divisive clustering, wherein agglomerative clustering we … In data mining and statistics, hierarchical clustering (also called hierarchical cluster analysis or HCA) is a method of cluster analysis that seeks to build a hierarchy of clusters. Strategies for hierarchical clustering generally fall into two categories: • Agglomerative: This is a "bottom-up" approach: Each observation starts in it…
