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 Semi-Implicit Variational Inference

Jen Ning Lim, Adam Michael Johansen

NeurIPS 2024spotlight

Semi-implicit variational inference (SIVI) enriches the expressiveness of variational families by utilizing a kernel and a mixing distribution to hierarchically define the variational distribution. Existing SIVI methods parameterize the mixing distribution using implicit distributions, leading to in…
