Why SGD is not Brownian Motion: A New Perspective on Stochastic Dynamics

Igor Ignashin, Anna Radovskaya, Andrew Semenov +7

Stochastic Gradient Descent (SGD) is commonly modeled as a Langevin process, assuming that minibatch noise acts as Brownian motion. However, this approximation relies on a continuo…
