October_preprints

Three new preprints on the arXiv! Wiener-space cubature for nonlinear Gaussian filtering uses tools from rough path theory to derive new, efficient filtering algorithms (led by my amazing intern Luke Snow); simulation-free learning of population dynamics with Wasserstein Lagrangian residuals extends our stitching approach to general Lagrangian actions in population dynamics; and Slaying the Hydra uses tools from actual causality to learn about interactions in large language models.
