Fast Flow-based Visuomotor Policies via Conditional Optimal Transport Couplings
Diffusion and flow matching policies have recently shown remarkable
performance in robotic applications by accurately capturing multimodal robot
trajectory distributions. However, their computationally expensive inference, due
to iterative denoising or numerical integration of an ODE, limits their application as
real-time controllers for robots. We introduce a methodology that utilizes Optimal
Transport couplings between noise and samples, in order to force straight solutions
