FOCUS: First-Order Control Using Optimal Transport Supervision for Imitation from Observations
Overview
This research presents FOCUS, a method that combines local optimal-transport alignment with short-horizon differentiable actor-critic learning to enable imitation learning from observations without requiring temporal correspondence between state-only demonstrations and expert trajectories.
