Prism-GRPO: Faster VLA Policy Optimization via Splitting Same-outcome Groups

Zeyun Deng, Yuzhe Lu, Yawei Wang +6

GRPO is increasingly used for reinforcement learning of vision-language-action (VLA) policies because, unlike PPO, it does not require training a critic. This simplification comes…

Analytical Correction for Subsampling Bias in Drifting Models

Jiaru Zhang, Zeyun Deng, Juanwu Lu +2

Drifting models are capable one-step generative models trained to follow a drifting field. The field combines attractive and repulsive softmax-weighted centroids over the data and…

Energy-Based Transfer for Reinforcement Learning

Zeyun Deng, Jasorsi Ghosh, Fiona Xie +3

Reinforcement learning algorithms often suffer from poor sample efficiency, making them challenging to apply in multi-task or continual learning settings. Efficiency can be improve…
