Cross-Embodiment Causal Transfer from Human Videos to Robot Manipulation
Xingyu Zhang, Yingchao Li, Peizheng Guo +3
Scaling robot manipulation models requires large amounts of interaction data, yet collecting diverse real-robot experience remains costly. Human manipulation videos, in contrast, p…
CAG-WAM: Causal Action-Gain World Action Models for Robot Manipulation
Peizheng Guo, Cheng Zhang, Xingyu Zhang +2
World Action Models (WAMs) combine action generation with future prediction, allowing predicted futures to support action evaluation and robot decision making. However, the future…
Temporal GRPO: Beyond Trajectory-Level Credit in Vision-Language-Action Reinforcement Learning
Yao Zhou, Hang Gao, Fengge Wu +2
Outcome-driven reinforcement learning offers a scalable way to post-train vision-language-action (VLA) policies from sparse task-success feedback. In common GRPO-based VLA post-tra…
PAPO-VLA: Planning-Aware Policy Optimization for Vision-Language-Action Models
Peizheng Guo, Jingyao Wang, Changwen Zheng +1
Vision-Language-Action (VLA) models show promising ability in language-guided robotic tasks. However, making VLA policies reliable remains challenging, because a manipulation task…
