The Loss Is Not Enough: Sampling Conditions and Inductive Bias in Contrastive Representation Learning
Researchers have developed a theoretical framework to understand contrastive learning, a method for self-supervised representation learning. Their work formalizes the 'diversity condition,' which is crucial for recovering meaningful latent geometry during the learning process. The study suggests that while standard settings ensure orthogonal recovery, restricted sampling can lead to non-orthogonal maps achieving lower losses, highlighting the interplay between sampling and architectural inductive bias.
