Momentum Particle Maximum Likelihood

Jen Ning Lim, Juan Kuntz, Samuel Power, Adam Michael Johansen

ICML 2024poster

Maximum likelihood estimation (MLE) of latent variable models is often recast as the minimization of a free energy functional over an extended space of parameters and probability distributions. This perspective was recently combined with insights from optimal transport to obtain novel particle-based…

Particle algorithms for maximum likelihood training of latent variable models

Juan Kuntz, Jen Ning Lim, Adam M. Johansen

AISTATS 2023poster

Neal and Hinton (1998) recast maximum likelihood estimation of any given latent variable model as the minimization of a free energy functional F, and the EM algorithm as coordinate descent applied to F. Here, we explore alternative ways to optimize the functional. In particular, we identify various…
