Efficiently Escaping Saddle Points under Generalized Smoothness via Self-Bounding Regularity
arXiv:2503.04712v3 Announce Type: replace-cross Abstract: We study the optimization of non-convex functions that are not necessarily smooth (gradient and/or Hessian are Lipschitz) using first order methods. Smoothness is a restrictive assumption in machine learning in both theory and practice, motivating significant recent work on finding first order stationary points of functions satisfying generalizations of smoothness with first order methods. We develop a novel framework that lets us systematically study the convergence of a large class of first-order optimization algorithms (which we call
Ongoing research in AI and machine learning continually seeks to improve efficiency and robustness of optimization algorithms for complex non-convex functions, driving this incremental but significant advancement.
Improved optimization techniques for non-convex functions can lead to more efficient and powerful AI models, particularly in deep learning where smoothness assumptions often don't hold.
This research provides a novel framework for analyzing first-order optimization algorithms under generalized smoothness conditions, potentially accelerating AI model development and deployment.
