Two new research papers explore advancements in optimization algorithms for machine learning. The first paper introduces a "Fast Regularized Policy Mirror Descent" method for reinforcement learning, offering improved convergence guarantees and sample complexity without requiring trajectory resets. The second paper presents "Averaged Mirror Descent" and dual gradient methods for entropic Gromov-Wasserstein problems, demonstrating convergence for a wider range of cost functions than previously possible and outperforming classical methods in certain scenarios.
