Mathematically this can be written as, Sim(C1,C2) = Min Sim(Pi,Pj) such that Pi ∈ C1 & Pj ∈ C2

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 …

It is based on grouping clusters in bottom-up fashion (agglomerative clustering), at each step combining two clusters that contain the closest pair of elements not yet belonging to the same cluster as each other.
