Adv-SSL: Adversarial Self-Supervised Representation Learning with Theoretical Guarantees

NeurIPS 2025poster

Learning transferable data representations from abundant unlabeled data remains a central challenge in machine learning. Although numerous self-supervised learning methods have been proposed to address this challenge, a significant class of these approaches aligns the covariance or correlation matri…

Fast Excess Risk Rates via Offset Rademacher Complexity

ICML 2023poster

Based on the offset Rademacher complexity, this work outlines a systematical framework for deriving sharp excess risk bounds in statistical learning without Bernstein condition. In addition to recovering fast rates in a unified way for some parametric and nonparametric supervised learning models wit…
