为对比学习 VC 维度建立了新的界限

研究人员改进了对具有间隔的对比学习的 VC 维度的理解。一篇新论文证明,具有 0 和 1 之间任意间隔 $\alpha$ 的对比学习的 VC 维度为 $O(n/\alpha^2)$,这比之前 $O(n\log(n)/\alpha^2)$ 的界限有所改进。该工作还建立了匹配的下界,表明导出的界限在常数因子内是最优的。 AI

影响 为对比学习中的泛化提供了理论基础,可能指导未来的表示学习方法。

    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 …
