新的预测散度掩码增强了LLM的强化学习

研究人员引入了一种称为预测散度掩码的新方法,用于改进大型语言模型(LLM)的强化学习。该技术解决了现有方法(如近端策略优化(PPO)和DPPO)的局限性,这些方法依赖于重要性比率,有时会与期望的策略更新相冲突。预测散度掩码旨在通过估计下一个策略梯度步骤是否会增加或减少概率散度来更好地使方向标准与邻近标准保持一致。这种方法在各种模型规模和精度设置的RL训练中都显示出了改进。 AI

影响 这种新方法可能导致更稳定、更高效的大型语言模型训练,从而可能提高它们在各种应用中的性能。

    LLM RL 的预测性散度掩码

    Reinforcement learning for large language models (LLMs) typically relies on trust-region masks to stabilize off-policy updates. The dominant PPO-style approach uses the sampled-token importance ratio for two criteria: a proximity criterion, which asks whether the policy has moved…
