New paper details nonasymptotic CLT for stochastic approximation in machine learning

A new paper published on arXiv introduces a nonasymptotic Wasserstein-1 central limit theorem (CLT) for linear two-time-scale stochastic approximation algorithms. This research addresses the need for understanding finite-time error rates in machine learning applications, improving upon existing analyses that focus on asymptotic convergence or suboptimal finite-time bounds. The derived CLT demonstrates that Polyak-Ruppert averaging can achieve an expected error decay rate of $1/\sqrt{K}$, a significant improvement over previous findings. AI
