English(EN) LP-SFT: Local-Preserving Supervised Fine-Tuning via Multimodal Entropy Structure

新的LP-SFT方法在微调过程中保留语言模型能力

研究人员推出了一种新颖的监督微调方法LP-SFT,旨在保留预训练语言模型固有的熵结构。标准的微调会因过度关注目标标签词元而损害现有能力。LP-SFT通过维持替代合理词元之间的相对结构来解决这个问题,从而在不牺牲采样多样性的情况下缓解能力退化。实验表明,LP-SFT在平衡准确性和更广泛的性能指标方面优于普通SFT和其他增强基线。 AI

影响 这项研究提供了一种改进语言模型微调的方法,有望在不牺牲预先存在的知识的情况下,实现更强大、更有能力的AI系统。
