VERPO框架通过基于证据的修正来增强语言模型训练

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员推出了一种名为VERPO（Verified Evidence Regularized Policy Optimization）的新型框架，用于增强语言模型的后训练。该方法使用可验证的结果奖励来指导改进，区分应保留或修改的token级决策。VERPO将无证据的参考恢复与有符号的token级证据修正分开，通过Fisher Evidence Contrast和ZPD控制器根据奖励对齐和成本来缩放接受度。在五个科学推理和工具使用任务中，VERPO在Qwen3-4B、Qwen3-8B和Llama-3.2-1B模型上均取得了改进。 AI

影响 VERPO的方法通过在训练过程中优化token级决策，有望带来更强大、更准确的语言模型。
