Semi-Empirical Objective Functions for Neural MCMC Proposal Optimization

no code implementations29 Sep 2021 Chris Cannella, Vahid Tarokh

Current objective functions used for training neural MCMC proposal distributions implicitly rely on architectural restrictions to yield sensible optimization results, which hampers the development of highly expressive neural MCMC proposal architectures.

Projected Latent Markov Chain Monte Carlo: Conditional Sampling of Normalizing Flows

no code implementations ICLR 2021 Chris Cannella, Mohammadreza Soltani, Vahid Tarokh

We introduce Projected Latent Markov Chain Monte Carlo (PL-MCMC), a technique for sampling from the high-dimensional conditional distributions learned by a normalizing flow.

Perception-Distortion Trade-off with Restricted Boltzmann Machines

no code implementations21 Oct 2019 Chris Cannella, Jie Ding, Mohammadreza Soltani, Vahid Tarokh

In this work, we introduce a new procedure for applying Restricted Boltzmann Machines (RBMs) to missing data inference tasks, based on linearization of the effective energy function governing the distribution of observations.
