Meta Flow Matching: Integrating Vector Fields on the Wasserstein Manifold

no code implementations26 Aug 2024 Lazar Atanackovic, Xi Zhang, Brandon Amos, Mathieu Blanchette, Leo J. Lee, Yoshua Bengio, Alexander Tong, Kirill Neklyudov

Flow-based models allow for learning these dynamics at the population level - they model the evolution of the entire distribution of samples.

Investigating Generalization Behaviours of Generative Flow Networks

1 code implementation7 Feb 2024 Lazar Atanackovic, Emmanuel Bengio

Since their inception, GFlowNets have proven to be useful for learning generative models in applications where the majority of the discrete space is unvisited during training.

A Computational Framework for Solving Wasserstein Lagrangian Flows

1 code implementation16 Oct 2023 Kirill Neklyudov, Rob Brekelmans, Alexander Tong, Lazar Atanackovic, Qiang Liu, Alireza Makhzani

The dynamical formulation of the optimal transport can be extended through various choices of the underlying geometry (kinetic energy), and the regularization of density paths (potential energy).

Simulation-free Schrödinger bridges via score and flow matching

1 code implementation7 Jul 2023 Alexander Tong, Nikolay Malkin, Kilian Fatras, Lazar Atanackovic, Yanlei Zhang, Guillaume Huguet, Guy Wolf, Yoshua Bengio

We present simulation-free score and flow matching ([SF]$^2$M), a simulation-free objective for inferring stochastic dynamics given unpaired samples drawn from arbitrary source and target distributions.

DynGFN: Towards Bayesian Inference of Gene Regulatory Networks with GFlowNets

1 code implementation NeurIPS 2023 Lazar Atanackovic, Alexander Tong, Bo wang, Leo J. Lee, Yoshua Bengio, Jason Hartford

In this paper we leverage the fact that it is possible to estimate the "velocity" of gene expression with RNA velocity techniques to develop an approach that addresses both challenges.
