New Kinetic Interacting Particle Langevin Monte Carlo methods introduced for statistical inference

This paper introduces Kinetic Interacting Particle Langevin Monte Carlo (KIPLMC) methods, a novel approach for statistical inference in latent variable models. The proposed diffusion process evolves parameters and latent variables jointly, with its stationary distribution concentrating around the maximum marginal likelihood estimate. Two explicit discretizations of this diffusion are presented as practical algorithms, achieving accelerated convergence rates in Wasserstein-2 distance, particularly for strongly concave log-likelihoods. The methodology's utility is demonstrated through numerical experiments applicable to unsupervised learning, statistical inference, and inverse problems. AI
