Amortised Inference through One-Step Implicit Sampling

Efficient sampling from Bayesian posterior distributions in high dimensions remains a hard problem, despite advances in theory and algorithms. Multiple steps are usually required to draw unbiased samples, for example, iterations of an MCMC algorithm or integration steps in a diffusion-based amortised sampler. However,...

Structured Inference with Large Language Gibbs

This work proposes Large Language Gibbs, a scheme for structured probabilistic inference that uses conditional distributions of an LLM as transition operators, and iteratively resample individual variables conditioned on others using an LLM's next-token conditionals to produce a stationary distribution.

Adaptive teachers for amortized samplers

The teacher, an auxiliary behavior model, is trained to sample high-loss regions of the student and can generalize across unexplored modes, thereby enhancing mode coverage by providing an efficient training curriculum.
