Clustering in machine learning.
Introduction. In Agglomerative Clustering, initially, each object/data is treated as a single entity or cluster. The algorithm then agglomerates pairs of data successively, i.e., it calculates the distance of each cluster with every other cluster. Two clusters with the shortest distance (i.e., those which are closest) merge and …
