**TLDR:** An approach that builds comparison-based visual systems by bringing similar examples closer and separating different ones in embedding space.

<p>Metric learning is crucial in visual problems where decisions are based on similarity rather than direct classification. It is widely used in face recognition, product matching, re-identification, and anomaly detection. The goal is to build an embedding space that is as discriminative and reliable as a good classifier. It is one of the central representation principles behind retrieval-oriented visual systems.</p>
