Webb19 juli 2024 · Langevin Monte Carlo relies on Langevin Dynamics to sample from a distribution. Langevin Dynamics describes the evolution of a system that is subject to random forces. Originally, Langevin Dynamics were used to describe Brownian motion. Webb12 juli 2024 · We introduce a new generative model where samples are produced via Langevin dynamics using gradients of the data distribution estimated with score matching. Because gradients can be ill-defined and hard to estimate when the data resides on low-dimensional manifolds, we perturb the data with different levels of Gaussian …
Choice of damping coefficient in Langevin dynamics
WebbThe underdamped version of the Langevin dynamics under log-Sobolev inequality is studied by Ma et al. [2024], where an iteration complexity for the discrete time algorithm that has better dependence on the dimension is provided. A coupling approach is used by Eberle et al. [2024] to quantify convergence to equilibrium for Langevin dynamics that ...
