Path-independent Flow Matching for Multi-parameter Generative Dynamics

Francisco Téllez, AmirHossein Zamani, Philippe Martin +5

Flow Matching is a powerful framework for learning transport maps between probability distributions. Yet its standard single-parameter formulation is not designed to capture multi-…

Simulation-free Schrödinger bridges via score and flow matching

Alexander Tong, Nikolay Malkin, Kilian Fatras +5

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

Improving and generalizing flow-based generative models with minibatch optimal transport

Alexander Tong, Kilian Fatras, Nikolay Malkin +5

Continuous normalizing flows (CNFs) are an attractive generative modeling technique, but they have been held back by limitations in their simulation-based maximum likelihood traini…
