WebIntroduction to Hierarchical Clustering. Hierarchical clustering groups data over a variety of scales by creating a cluster tree or dendrogram. The tree is not a single set of clusters, but rather a multilevel hierarchy, where clusters at one level are joined as clusters at the next level. This allows you to decide the level or scale of ... Web4 de dez. de 2024 · In practice, we use the following steps to perform hierarchical clustering: 1. Calculate the pairwise dissimilarity between each observation in the dataset. First, we must choose some distance metric – like the Euclidean distance – and use this metric to compute the dissimilarity between each observation in the dataset.
