Web20 de dez. de 2024 · In this section, we will learn about how to make scikit learn hierarchical clustering examples in python. As we know hierarchical clustering categories similar objects into groups. It treats each cluster as a separate cluster. It identifies the two cluster which is very near to each other. And merger the two most similar clusters. Webscipy.cluster.hierarchy.ward¶ scipy.cluster.hierarchy.ward(y) [source] ¶ Performs Ward’s linkage on a condensed distance matrix. See linkage for more information on the return structure and algorithm. The following are common calling conventions: Z = ward(y) Performs Ward’s linkage on the condensed distance matrix y.
