Webscipy.hierarchy ¶. The hierarchy module of scipy provides us with linkage() method which accepts data as input and returns an array of size (n_samples-1, 4) as output which iteratively explains hierarchical creation of clusters.. The array of size (n_samples-1, 4) is explained as below with the meaning of each column of it. We'll be referring to it as an … Webfrom scipy import cluster Z = cluster. hierarchy. linkage (X, "complete") cluster. hierarchy. dendrogram (Z); The height of each little “bracket” is representative of the distance …
