arXiv:2606.30455v1 Announce Type: new Abstract: The standard convergence analysis of mini-batch stochastic gradient descent (SGD) models gradient noise using a single variance term that treats all parameter directions equally, ignoring the fact that noise in high-curvature directions has less impact because learning rates are already constrained there. We introduce Curvature-Weighted Gradient Diversity (CWGD), a geometry-aware measure that weights per-sample gradient diversity by the inverse square root of the Hessian, providing a tighter proxy for the effective optimization noise.

The paper introduces a novel approach to optimizing SGD, a core AI training algorithm, by accounting for geometric properties of the loss landscape, addressing longstanding limitations.
Improved SGD optimization can lead to faster, more efficient, and potentially more stable training of complex AI models, impacting the overall cost and accessibility of advanced AI.
The understanding and practical implementation of gradient noise in stochastic optimization for AI models may evolve, leading to new algorithms and possibly better performing AI systems.
