In this chapter, we're going to discuss a particular clustering technique called hierarchical clustering. Instead of working with the relationships existing in the whole dataset, this approach starts with a single entity containing all elements (divisive) or N separate elements (agglomerative), and proceeds by splitting or merging the clusters according to some specific criteria, which we're going to analyze and compare.

Overview of this book
In this book, you will learn all the important machine learning algorithms that are commonly used in the field of data science. These algorithms can be used for supervised as well as unsupervised learning, reinforcement learning, and semi-supervised learning. The algorithms that are covered in this book are linear regression, logistic regression, SVM, naïve Bayes, k-means, random forest, TensorFlow and feature engineering.
In this book, you will how to use these algorithms to resolve your problems, and how they work. This book will also introduce you to natural language processing and recommendation systems, which help you to run multiple algorithms simultaneously.
On completion of the book, you will know how to pick the right machine learning algorithm for clustering, classification, or regression for your problem
