New bounds established for contrastive learning VC dimension

By PulseAugur Editorial · [1 sources] ·

Researchers have improved the understanding of the VC dimension for contrastive learning with a margin. A new paper proves that the VC dimension for contrastive learning with any margin $\alpha$ between 0 and 1 is $O(n/\alpha^2)$, which is an improvement over the previous bound of $O(n\log(n)/\alpha^2)$. The work also establishes matching lower bounds, showing the derived bounds are optimal up to constant factors. AI

IMPACT Provides theoretical underpinnings for generalization in contrastive learning, potentially guiding future representation learning methods.

    Optimal VC Dimension of Contrastive Learning with Margin

    arXiv:2609.38834v1 Announce Type: cross Abstract: Contrastive learning is a successful paradigm for learning $d$-dimensional geometric representations from a collection of ``anchor--positive--negative'' triplets $(i,j^{+},k^{-})$, indicating that ``item $i$ is closer to $j$ than …
