Researchers have introduced Echo, a novel single-stage framework designed to enhance the efficiency of visual reinforcement learning (RL). Echo addresses the high computational costs associated with visual RL by employing inverse distillation, where a state-based auxiliary policy collects inexpensive, unrendered experience. This collected experience is then used for off-policy value learning, directly improving the visual policy. Initial evaluations on various control and manipulation tasks demonstrate significant reductions in time to achieve reference returns and improvements in peak mean returns compared to existing methods.
