新研究探索自适应秩分配以实现高效的LLM微调

作者 PulseAugur 编辑部 · [3 个来源] ·

两篇新研究论文介绍了参数高效微调（PEFT）大型语言模型的先进方法。第一篇论文提出了LAARA框架，该框架根据轻量级Fisher估计动态地为不同的Transformer层分配适配器秩，在GLUE和MathInstruct等基准测试中的参数效率和性能方面优于LoRA和AdaLoRA等现有方法。第二篇论文StatLoRA将秩分配视为一个统计假设检验问题，利用从AdamW等优化器的渐近正态性理论导出的估计p值来确定保留哪些组件。实验表明，StatLoRA在DeBERTaV3-base和Qwen2.5-7B等各种任务和模型上取得了与 vanilla LoRA 和其他自适应方法相当或更好的结果。 AI

影响 这些方法提供了更有效的方式来适应大型语言模型，有可能降低计算成本并实现更广泛的微调应用。
