研究将学习率与大型语言模型中的灾难性过度拟合联系起来

一篇新的研究论文探讨了学习率在大型语言模型(LLMs)的监督微调(SFT)过程中如何影响灾难性过度拟合。该研究发表在arXiv上,表明即使在相同的SFT损失下进行训练,不同的学习率也会导致定性上不同的模型。具体而言,研究表明学习率衰减会增加预训练模型的尖锐度,进而加剧SFT过程中的遗忘和过度拟合。 AI

影响 为理解大型语言模型训练动态提供了见解,可能指导微调策略以减轻性能下降。

    学习率如何调节灾难性过度拟合

    arXiv:2604.13627v2 Announce Type: replace-cross Abstract: Supervised fine-tuning (SFT) is a common first stage of LLM post-training, teaching the model to follow instructions and shaping its behavior as a helpful assistant. At the same time, SFT may harm the fundamental capabilit…
