新的RLVR方法增强LLM的鲁棒性和泛化能力 · 跟踪2个来源

研究人员开发了新的方法来提高多模态大语言模型(LLM)的强化学习可验证奖励(RLVR)的鲁棒性和泛化能力。第一种方法是提示不变RLVR(PIRL),它将奖励信号中的格式与内容分离,并在语义等价提示上应用策略不变性,与GRPO相比,在压力测试下准确率下降显著降低。第二种方法是扰动参数策略优化(3PO),它通过从后验采样不同的策略来探索参数空间,在OLMo-3-1025-7B和Qwen2.5-Math-7B等模型上,对于数学推理和代码生成等下游任务,在计算成本略有增加的情况下,表现出了一致的性能提升。 AI

影响 这些进展通过提高LLM在多样化输入下泛化和保持准确性的能力,有望在复杂、高风险的应用中实现更可靠、更高性能的LLM。
