Two new research papers explore the convergence properties of stochastic gradient descent (SGD) methods under challenging conditions. The first paper analyzes SGD with gradient clipping and additive Gaussian noise, proving almost sure convergence under smoothness and bounded noise assumptions. The second paper investigates SGD under heavy-tailed noise and Hölder smoothness, establishing new convergence rates for standard SGD, $\delta$-GClip, and G-Clip, including the first guarantee for a stochastic gradient method in a very heavy-tailed regime.
