GROW: Aligning GRPO with State-Action Modeling for Open-World VLM Agents
The paper introduces GROW, a reinforcement learning framework designed for open-world vision-language model agents. It addresses limitations in existing methods that rely on supervised fine-tuning by utilizing Group Relative Policy Optimization in a more effective manner. Experiments demonstrate that GROW achieves state-of-the-art performance on over 800 Minecraft tasks.
- ▪GROW decomposes collected trajectories into state-action samples for better reinforcement learning performance.
- ▪The framework computes advantages between these samples rather than treating full trajectories as single entities.
- ▪Experiments show that GROW achieves state-of-the-art performance in open-world tasks.
