Forward-backward Gaussian variational inference via JKO in the Bures-Wasserstein Space
Michael Diao, Krishnakumar Balasubramanian, Sinho Chewi +1
Variational inference (VI) seeks to approximate a target distribution by an element of a tractable family of distributions. Of key interest in statistics and machine learning i…

Faster high-accuracy log-concave sampling via algorithmic warm starts
Jason M. Altschuler, Sinho Chewi
Understanding the complexity of sampling from a strongly log-concave and log-smooth distribution on to high accuracy is a fundamental problem, both from a practi…

Improved Discretization Analysis for Underdamped Langevin Monte Carlo
Matthew Zhang, Sinho Chewi, Mufan Bill Li +2
Underdamped Langevin Monte Carlo (ULMC) is an algorithm used to sample from unnormalized densities by leveraging the momentum of a particle moving in a potential well. We provide a…
