About the Workshop

This workshop brings together recent advances in probabilistic modeling, with a focus on emerging methods for representing, learning, and sampling complex probability distributions. Topics of interest include kernel and transport-based methods, discrete and structured generative models, conditional and constrained modeling, and new perspectives on density modeling and sampling.

The workshop also highlights scientific applications of these ideas, including molecular dynamics, inverse problems, climate and weather modeling, and related problems in the physical and life sciences. More broadly, it aims to bring together researchers from machine learning, statistics, applied mathematics, and computational science to discuss common ideas, emerging challenges, and new opportunities in modern probabilistic modeling.

Topics of Interest

Kernel & Transport Methods

Optimal transport, kernel-based sampling, and flow-based approaches for distribution modeling

Generative Models

Discrete sampling and generative modeling via diffusion models and flow matching

Sampling & Density

Advanced MCMC methods, diffusion-based sampling, and density estimation

Conditional & Constrained

Conditional generation, constrained optimization, and model steering

Scientific Applications

Probabilistic methods for PDEs, molecular simulation, free energy estimation, biology, and climate and weather modeling

Speakers

We are excited to feature talks from leading researchers in probabilistic modeling, machine learning, and scientific applications.
