Data Science and Machine Learning (Theory and Projects) A to Z - Introduction to Machine Learning: Unsupervised Learning

The video tutorial explains the differences between supervised, unsupervised, and reinforcement learning. It begins by discussing why some learning routines are termed supervised, indicating the existence of unsupervised routines. Unsupervised learning is illustrated with examples of clustering, where objects are grouped based on similarities. The tutorial then transitions to the concept of classification within unsupervised learning. Finally, it introduces reinforcement learning, highlighting its unique characteristics and differences from the other paradigms.

Describe the classification problem in relation to unsupervised learning.
