ExGRPO: Learning to Reason from Experience
arXiv – CS AI|Runzhe Zhan, Yafu Li, Zhi Wang, Xiaoye Qu, Dongrui Liu, Jing Shao, Derek F. Wong, Yu Cheng||3 views
🤖AI Summary
Researchers introduce ExGRPO, a new framework that improves AI reasoning by reusing and prioritizing valuable training experiences based on correctness and entropy. The method shows consistent performance gains of +3.5-7.6 points over standard approaches across multiple model sizes while providing more stable training.
Key Takeaways
- →ExGRPO addresses inefficiencies in current reinforcement learning approaches that discard training experiences after single use.
- →The framework identifies rollout correctness and entropy as key indicators of valuable learning experiences.
- →Testing across five models (1.5B-8B parameters) showed consistent reasoning improvements on mathematical and general benchmarks.
- →The method provides more stable training for both stronger and weaker models where traditional on-policy methods fail.
- →Results demonstrate that principled experience management is crucial for efficient and scalable AI reasoning training.
