arXiv:2606.00520v1 Announce Type: cross Abstract: Many stochastic gradient methods are believed not to converge when the noise in stochastic gradients has only a finite $p$-th moment for $p\in\left(1,2\right)$, a setting known as the heavy-tailed noise assumption. However, some recent studies have found that Stochastic Gradient Descent ($\textsf{SGD}$), without any modification to its update rule, can surprisingly converge in expectation for convex problems with bounded domains, highlighting the potential of classical stochastic gradient methods. Inspired by this recent progress, we provide a
This paper represents continued academic inquiry into the theoretical underpinnings of AI optimization, specifically addressing a known challenge in stochastic gradient methods when encountering heavy-tailed noise.
Improved theoretical understanding of SGD's convergence under challenging noise conditions can lead to more robust and efficient AI models, reducing computational waste and improving reliability for certain applications.
The understanding that classical SGD can converge in expectation even with heavy-tailed noise suggests that some perceived limitations of fundamental optimization algorithms might be less restrictive than previously assumed.
