Two new research papers explore advanced techniques for sampling from complex probability distributions, a critical task in machine learning. The first paper, submitted to arXiv, focuses on variance reduction methods like SGD with momentum, STORM, and PAGE for non-log-concave distributions, establishing improved convergence rates and demonstrating their effectiveness in imaging applications. The second paper, also on arXiv, introduces a randomized midpoint method for log-concave sampling under constraints, providing new convergence guarantees for Langevin algorithms in constrained domains and showing near-optimal results.
