Dynamic Conditional Optimal Transport through Simulation-Free Flows

no code implementations5 Apr 2024 Gavin Kerrigan, Giosue Migliorini, Padhraic Smyth

We study the geometry of conditional optimal transport (COT) and prove a dynamical formulation which generalizes the Benamou-Brenier Theorem.

Precipitation Downscaling with Spatiotemporal Video Diffusion

no code implementations11 Dec 2023 Prakhar Srivastava, Ruihan Yang, Gavin Kerrigan, Gideon Dresdner, Jeremy McGibbon, Christopher Bretherton, Stephan Mandt

In climate science and meteorology, high-resolution local precipitation (rain and snowfall) predictions are limited by the computational costs of simulation-based methods.

Functional Flow Matching

no code implementations26 May 2023 Gavin Kerrigan, Giosue Migliorini, Padhraic Smyth

We propose Functional Flow Matching (FFM), a function-space generative model that generalizes the recently-introduced Flow Matching model to operate in infinite-dimensional spaces.

Diffusion Generative Models in Infinite Dimensions

1 code implementation1 Dec 2022 Gavin Kerrigan, Justin Ley, Padhraic Smyth

We generalize diffusion models to operate directly in function space by developing the foundational theory for such models in terms of Gaussian measures on Hilbert spaces.
