arXiv:2602.09842v2 Announce Type: replace-cross Abstract: We present a theoretical analysis of stochastic optimization methods in terms of their sensitivity with respect to the step size. We identify a key quantity that, for each method, describes how the performance degrades as the step size becomes too large. For convex problems, we show that this quantity directly impacts the suboptimality bound of the method. Most importantly, our analysis provides direct theoretical evidence that adaptive step-size methods, such as SPS or NGN, are more robust than SGD. This allows us to quantify the advan
The continuous drive for more efficient and reliable AI training necessitates deeper theoretical understanding of optimization algorithms, particularly as models scale and computational resources become a bottleneck.
Improved stability and robustness in stochastic optimization directly translates to more efficient and reliable training of large-scale AI models, reducing computational waste and accelerating model development.
The theoretical evidence favoring adaptive step-size methods over traditional SGD will likely accelerate their adoption and refinement, shifting the paradigm for AI model training best practices.
