Trust Region Masking for Long-Horizon LLM Reinforcement Learning

Yingru Li, Jiacai Liu, Jiawei Xu +4

Policy gradient methods for Large Language Models optimize a policy I¨€I^​¸ via a surrogate objective computed from samples of a rollout policy I¨€roll​. However, modern…

The Optimal Token Baseline: Variance Reduction for Long-Horizon LLM-RL

Yingru Li, Jiawei Xu, Ziniu Li +10

Reinforcement Learning (RL) for Large Language Models (LLMs) often suffers from training collapse in long-horizon tasks due to exploding gradient variance. To mitigate this, a base…

Dynamic Vocabulary Pruning: Stable LLM-RL by Taming the Tail

Yingru Li, Jiawei Xu, Jiacai Liu +6

Reinforcement Learning (RL) for Large Language Models (LLMs) faces a fundamental tension: the numerical divergence between high-throughput inference engines and numerically precise…
