DexPIE: Stable Dexterous Policy Improvement from Real-World Experience
Researchers have developed DexPIE, a new framework designed to improve the performance of dexterous manipulation policies trained through imitation learning. This post-training system leverages real-world deployment experience to overcome the limitations of relying solely on expert demonstrations. DexPIE incorporates an intervention system for better exploration and a DAgger-style data collection method, alongside asynchronous inference and an optimality indicator to refine policy learning. In tests across three complex tasks, DexPIE demonstrated a 37% increase in success rate compared to baseline methods. AI
