Researchers have developed a new framework called Manifold-Constrained Adversarial Training (MCAT) to improve the robustness of adversarial training on datasets with long-tailed class distributions. MCAT addresses the issue where tail classes experience higher robust errors and unstable decision boundaries by enforcing semantic validity of adversarial examples. The method penalizes deviations from class-conditional manifolds and promotes balanced geometric separation between classes, leading to improved adversarial robustness across all classes. AI
