WebIn hierarchical clustering, the required number of clusters is formed in a hierarchical manner. For some n number of data points, initially we assign each data point to n clusters, i.e., each point in a cluster in itself. Thereafter, we merge two points with the least distance between them into a single cluster. WebHierarchical clustering is where you build a cluster tree (a dendrogram) to represent data, where each group (or “node”) links to two or more successor groups. The groups are nested and organized as a tree, which ideally …
