Definition

A way to teach AI without telling it the correct answers. The model looks at lots of data and tries to find patterns, groups, or trends all by itself. It learns what things are similar or different without needing labels.

Example

“Unsupervised learning can group customers by shopping habits without knowing anything about them ahead of time.”

How It’s Used in AI

Used in recommendation engines, market segmentation, fraud detection, and image clustering. It’s great for exploring big datasets when you don’t have labeled data but still want to find useful patterns.

Pro Tip

Use unsupervised learning when you don’t know what to look for—AI will help you discover hidden insights you might miss.
