New SKooP method boosts reinforcement learning for robot locomotion

By PulseAugur Editorial · [3 sources] ·

Researchers have developed SKooP (Symmetric Koopman Predictions), a novel approach to enhance reinforcement learning for legged robot locomotion. This method combines morphological symmetries with a Koopman model learned via an autoencoder to improve policy learning efficiency and generalizability. SKooP integrates learned Koopman predictions as privileged observations for the critic, enabling learning from smoother features, and incorporates group symmetries into the actor and critic networks for a more equivariant policy. The approach has demonstrated consistent reductions in convergence time and increases in learned reward for challenging bipedal locomotion tasks on a quadruped robot, with policies showing transferability to different simulation environments.
