A new paper details the high-dimensional behavior of stochastic gradient descent (SGD) on diagonal linear networks. The research shows that in high dimensions, SGD dynamics can be accurately modeled by a stochastic differential equation. This allows for the derivation of a deterministic partial differential equation that tracks key statistics like risk and curvature, ultimately demonstrating exponential convergence to zero risk. AI
