Researchers have developed new methods for optimizing machine learning algorithms, particularly in the context of nonconvex optimization and scientific computing. One paper introduces a black-box online-to-nonconvex conversion technique that leverages static regret minimization oracles, resolving an open problem and offering a new perspective on adaptive optimization methods like AdaGrad and Shampoo. Another study presents PCGBandit, a one-shot acceleration method for transient partial differential equation solvers that uses bandit algorithms to adaptively learn solver configurations directly from simulation data, demonstrated effectively on fluid and magnetohydrodynamics problems using OpenFOAM.
