Clustering

As explained in The AI Pocket Book

An unsupervised learning method that groups similar data points into clusters.

How The AI Pocket Book covers it

How deep it goes

Defines grouping and illustrates ambiguity, but does not explain clustering algorithms or internal mechanics.

Examples

Uses patient medical records, alternative cluster counts, and the knee or elbow curve heuristic.

What it assumes

Assumes no labeled right outputs and establishes the distinction from supervised learning.

What you can do after

Apply clustering to explore data while judging its groupings as non-unique and difficult to validate.

How it connects

Connects clustering with unsupervised learning and contrasts it with supervised learning.
