Shifted Composition III: Local Error Framework for KL Divergence
Jason M. Altschuler, Sinho Chewi
Coupling arguments are a central tool for bounding the deviation between two stochastic processes, but traditionally have been limited to Wasserstein metrics. In this paper, we app…
Uniform-in- log-Sobolev inequality for the mean-field Langevin dynamics with convex energy
Sinho Chewi, Atsushi Nitanda, Matthew S. Zhang
We establish a log-Sobolev inequality for the stationary distribution of mean-field Langevin dynamics with a constant that is independent of the number of particles . Our proof…
Sampling from the Mean-Field Stationary Distribution
Yunbum Kook, Matthew S. Zhang, Sinho Chewi +2
We study the complexity of sampling from the stationary distribution of a mean-field SDE, or equivalently, the complexity of minimizing a functional over the space of probability m…
Fast parallel sampling under isoperimetry
Nima Anari, Sinho Chewi, Thuy-Duong Vuong
We show how to sample in parallel from a distribution over that satisfies a log-Sobolev inequality and has a smooth log-density, by parallelizing the Langevin (re…
