New SUDO framework enables faster, more flexible unbalanced optimal transport

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SUDO, a novel framework for Simulation-free Unbalanced Dynamic Optimal Transport (UDOT) that handles general non-quadratic convex growth penalties. This method bypasses the need for computationally intensive NeuralODE simulations or analytical solutions, which were previously limited to quadratic penalties like Wasserstein-Fisher-Rao (WFR). SUDO learns conditional paths and transport costs, then uses unbalanced flow matching for a simulation-free solution, achieving comparable accuracy to existing methods while significantly improving computational speed.

    Simulation-free Unbalanced Dynamic Optimal Transport with General Growth Penalty

    arXiv:2609.04710v1 Announce Type: cross Abstract: Inferring cellular dynamics from unpaired single-cell snapshots requires modeling both state transitions and population growth or death. Unbalanced dynamic optimal transport (UDOT) addresses this by penalizing growth along transpo…
