Initially, each data point is considered as an individual cluster in this technique. After each iteration, the similar clusters merge with other clusters and the merging will stop until one cluster or K clusters are formed.
WebHierarchical Clustering. Hierarchical clustering is an unsupervised learning method for clustering data points. The algorithm builds clusters by measuring the dissimilarities between data. Unsupervised learning means that a model does not have to be trained, and we do not need a "target" variable. This method can be used on any data to ... WebBelow is how agglomerative clustering algorithm works: Initialize the algorithm: Begin by treating each data point as a separate cluster.. Compute the pair wise distances: Compute the distance between all pairs of clusters using a specified distance metric.This produces a distance matrix that represents similarity between clusters.
