Hierarchy linkage
Web16 de jan. de 2024 · We have seen in the previous post about Hierarchical Clustering, when it is used and why. We glossed over the criteria for creating clusters through dissimilarity measure which is typically the Euclidean distance between points. There are other distances that can be used like Manhattan and Minkowski too while Euclidean is the one most … WebHierarchical 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 visualize and interpret the ...
