Unsupervised Learning

In Unsupervised Learning, the machine uses unlabeled data and learns on itself without any supervision. The machine tries to find a pattern in the unlabeled data and gives a response.

Introduction

Unsupervised learning can be further grouped into types:

  1. Clustering - Clustering is the method of dividing the objects into clusters that are similar between them and are dissimilar to the objects belonging to another cluster. 
  2. Association - Association is a rule-based machine learning to discover the probability of the co-occurrence of items in a collection.
