新方法RSTG通过自适应教师指导改进LLM强化学习

研究人员开发了RSTG(Recovering Learning Signals via Adaptive Teacher Guidance,通过自适应教师指导恢复学习信号),一种改进大型语言模型强化学习的新方法。现有的GRPO等方法在稀疏奖励方面存在困难,而与在线蒸馏(OPD)的简单组合可能会降低性能。RSTG选择性地将蒸馏应用于负面提示,根据教师的置信度对样本进行加权,并针对特定标记进行蒸馏。它还通过注入正梯度来纳入教师生成的轨迹上的监督微调(SFT)。实验表明,RSTG在数学和代码任务上的表现显著优于标准方法。 AI

影响 这项研究通过提高强化学习技术的效率和有效性,有望带来更强大的LLM。
