Exploratory Memory-Augmented LLM Agent via Hybrid On- and Off-Policy Optimization
🤖AI Summary
Researchers propose EMPO², a new hybrid reinforcement learning framework that improves exploration capabilities for large language model agents by combining memory augmentation with on- and off-policy optimization. The framework achieves significant performance improvements of 128.6% on ScienceWorld and 11.3% on WebShop compared to existing methods, while demonstrating superior adaptability to new tasks without requiring parameter updates.
Key Takeaways
- →EMPO² addresses the key bottleneck of exploration in LLM agents trained with reinforcement learning.
- →The hybrid framework leverages memory for exploration while combining on- and off-policy updates for robust performance.
- →Performance improvements of 128.6% on ScienceWorld and 11.3% on WebShop demonstrate significant advancement over existing GRPO methods.
- →The framework shows superior adaptability in out-of-distribution tests, requiring only few trials with memory and no parameter updates.
- →EMPO² represents a promising approach for building more exploratory and generalizable LLM-based agents.
