Let’s find out how. Unsupervised Learning - Clustering "Clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters). However, this is just a demo to show how clustering for text dataset can be done and it produces good results. It is very useful for data mining and big data because it automatically finds patterns in the data, without the need for labels, unlike supervised machine learning.
