Two new research papers explore the theoretical underpinnings of empirical risk minimization (ERM) in machine learning. The first paper, "Replica Symmetry Breaking and Algorithmic Thresholds in Empirical Risk Minimization under Multi-Index Model," introduces an incremental approximate message passing (IAMP) algorithm to analyze ERM performance in high-dimensional settings, aiming to characterize the optimal performance achievable by polynomial-time algorithms. The second paper, "Universality of empirical risk minimization," proves general universality results for train and test errors in ERM, demonstrating that under certain conditions, the minimum value depends only on the asymptotic mean and covariance of the data distribution, extending previous findings beyond strongly convex loss functions.
