Web26 de nov. de 2024 · Hierarchical Clustering Python Example. Here is the Python Sklearn code which demonstrates Agglomerative clustering. Pay attention to some of the following which plots the Dendogram. Dendogram is used to decide on number of clusters based on distance of horizontal line (distance) at each level. The number of clusters chosen is 2. WebHierarchical clustering is a popular method for grouping objects. It creates groups so that objects within a group are similar to each other and different from objects in other groups. Clusters are visually represented in a hierarchical tree called a dendrogram. Hierarchical clustering has a couple of key benefits:
