Non-negative Gauss-Newton Methods for Empirical Risk Minimization
Explore a distinguished seminar on optimization and data featuring Lin Xiao from Facebook AI Research. Delve into non-negative Gauss-Newton methods for empirical risk minimization, focusing on minimizing the average of numerous smooth but potentially non-convex functions. Learn how reformulating non-negative loss functions allows for the application of Gauss-Newton or Levenberg-Marquardt methods, resulting in highly adaptive algorithms. Discover the convergence analysis of these methods in convex, non-convex, and stochastic settings, comparing their performance to classical gradient methods. Gain insights from Lin Xiao's extensive experience in optimization theory and algorithms for deep learning and reinforcement learning, drawing from his work at Meta's Fundamental AI Research team and previous roles at Microsoft Research and top academic institutions.
