## TL;DR

Representation learning studies how models learn useful features from data, including deep, distributed, and word-vector representations. This repair maps claims to canonical papers.

## Core Explanation

The previous entry had claim-confidence mismatch. This version aligns facts to direct sources and medium claim confidence.
