Researchers have developed new sampling bounds for regularized classification, achieving optimal $(1\pm\varepsilon)$-relative error for a wide range of Lipschitz continuous loss functions. The study presents improved sampling complexity bounds, specifically $k^2/\varepsilon^2$ for L2 regularization and $k/\varepsilon^2$ for L1 regularization. These findings rely on simple uniform or norm sampling and offer a significant improvement over previous sensitivity sampling bounds, utilizing refined arguments to avoid overcounting issues. AI
