Parallelizing MCMC Across the Sequence Length

David Zoltowski*, Skyler Wu*, Xavier Gonzalez, Leo Kozachkov, Scott W. Linderman

Paper Code

arXiv 2025; To appear in NeurIPS 2025

We develop methods to parallelize Gibbs, MALA, and HMC sampling across the chain length using parallel Newton methods.
Predictability Enables Parallelization of Nonlinear State Space Models

Xavier Gonzalez, Leo Kozachkov, David Zoltowski, Kenneth L. Clarkson, Scott W. Linderman

A general recurrent state space framework for modeling neural dynamics during decision-making

David Zoltowski, Jonathan W Pillow, Scott W Linderman
