If you’ve browsed Google News, you’ll have noticed that articles on similar topics are grouped together. Google scans for new articles, and then analyzes the text to decide which articles talk about the same topic. This is an example of cluster analysis, which we'll learn about in this tutorial.

Cluster Analysis in Python

Preface

If you’ve browsed through Google News, you’ll most likely have noticed that news articles on similar topics are grouped together. Google scans the Internet for new articles, and then analyzes the text within each of them to decide which articles talk about the same topic! It’s essentially a result of an unsupervised machine learning algorithm. Cluster analysis is an example of an unsupervised learning algorithm. Another example of clustering is trending topics on Twitter. Twitter goes through new tweets in real time to determine words, hashtags, and a combination of them, to determine what’s causing a buzz.
