arXiv:2605.31309v1 Announce Type: new Abstract: We survey Lyapunov-based techniques for the finite-time analysis of stochastic iterative algorithms, also known as stochastic approximation (SA) algorithms, for solving fixed-point equations $\bar{F}(x)=x$, where the operator $\bar{F}(\cdot)$ can only be accessed through a noisy oracle. We first focus on the standard setting in which $\bar{F}(\cdot)$ is contractive with respect to some norm and the noise is i.i.d., and explain how generalized Moreau envelopes serve as universal Lyapunov functions, regardless of the underlying norm. We then show h
This research provides a more robust mathematical framework for understanding and optimizing stochastic iterative algorithms, which are foundational to many modern AI and machine learning systems.
Improved theoretical guarantees and convergence analysis for these algorithms can lead to more stable, efficient, and reliable AI models, impacting diverse applications from autonomous systems to scientific discovery.
The development of universal Lyapunov functions for generalized Moreau envelopes offers a unified approach to analyzing stochastic algorithms, potentially accelerating research and development in optimization.
