Remember it this wayBring related examples together; separate the rest.
In plain language
Contrastive learning teaches a model by comparing examples. Representations of related examples are pulled closer together, while representations of unrelated examples are pushed apart.
Why it matters
The method can learn useful representations without a manually written label for every example. Its behavior still depends on how positive and negative pairs are created.
Example
Two altered views of the same photograph are treated as a positive pair, while views from different photographs are treated as negatives.
Common misconception
Contrastive learning is not automatically unbiased or label-free. The pairing rules act as supervision and can encode assumptions about what should count as similar.
