In this tutorial, we will implement the naive approach to hierarchical clustering. It is naive in the sense that it is a fairly general procedure, which unfortunately operates in O (n 3) runtime and O (n 2) memory, so it does not scale very well. For some linkage criteria, there exist optimized algorithms ...

WebThe algorithm will merge the pairs of cluster that minimize this criterion. ‘ward’ minimizes the variance of the clusters being merged. ‘average’ uses the average of the distances of each observation of the two sets. ‘complete’ or ‘maximum’ linkage uses the maximum distances between all observations of the two sets.
