Introduction

Welcome to the session on ‘Hierarchical Clustering’. In the previous sessions, you got a basic understanding of what clustering is and how you can use the K-Means algorithm to create clusters in your data set. You also saw the execution of the K-Means algorithm in python.

In this session

You will learn about another algorithm to achieve unsupervised clustering. This is called Hierarchical Clustering. Here, instead of pre-defining the number of clusters, you first have to visually describe the similarity or dissimilarity between the different data points and then decide the appropriate number of clusters on the basis of these similarities or dissimilarities.

You will learn about:

  • Hierarchical clustering algorithm.
  • Interpreting the dendrogram.
  • Cutting the dendrogram.
  • Types of linkages.
