# What is Hierarchical Clustering?

Hierarchical Clustering is a technique to group objects based on distance or similarity. Hierarchical Clustering is often called as unsupervised learning because we let the machine (computer) learns mere from objects with their features and then the machine will automatically categorize those objects into groups. We do not specify which the objects suppose to be clustered into which group. In this hierarchical clustering tutorial, you will learn by numerical examples step by step on how to compute manually hierarchical clustering using agglomerative technique and validate the clustering using Cophenetic Correlation Coefficient in a very simple explanation.
