English(EN) Learning Beyond What You Sample: Off-Policy-Aware Cross-Model Trajectory Exchange for RLVR

GRAFT框架通过实现跨模型轨迹交换来增强RLVR

研究人员开发了GRAFT,一个旨在改进具有可验证奖励的强化学习(RLVR)方法(如GRPO)的新框架。GRAFT解决了RLVR中有限的rollout预算问题,这可能导致生成零成功轨迹的情景,从而提供零策略梯度信号。通过利用异构模型的互补优势,GRAFT通过交换成功和不成功的轨迹来实现互惠学习。该框架在数学推理基准上持续提升模型性能,在相同的rollout预算下优于GRPO。 AI

影响 这项研究引入了一种通过使模型能够从彼此的轨迹中学习来提高强化学习效率的方法,有可能降低训练成本并提高复杂任务的性能。

    学习超越所采样内容:用于 RLVR 的策略外感知跨模型轨迹交换

    Reinforcement Learning with Verifiable Rewards (RLVR) methods such as GRPO rely on successful self-generated trajectories, but finite rollout budgets can produce all-fail groups with no reward-based policy-gradient signal. While additional rollouts improve the chance of success a…
