ProWorld: Multi-View World Model with Proprioceptive Feedback for Closed-Loop Policy Evaluation
Zijun Wang, Tianyi Yan, Haokun Lin +12
Evaluating robot manipulation policies through repeated physical trials is costly. We study whether an action-conditioned world model can serve as a closed-loop test environment wh…
