Researchers have developed new methods to analyze the generalization capabilities of Stochastic Gradient Descent (SGD) in machine learning. One paper introduces predictable history-adaptive virtual perturbations, allowing for more accurate generalization bounds by accounting for adaptive noise geometries that depend on the optimization history. Another study examines the high-dimensional scaling limits of online SGD in single-layer networks, revealing how critical step sizes and information exponents influence sample complexity and the emergence of stochastic fluctuations.
