摘要
近期研究揭示了低秩适应（LoRA）方法在微调大型语言模型时的局限性，特别是在多步骤程序知识的背景下。研究发现，LoRA在复杂程序理解要求高的任务中，表现始终低于传统的完全微调方法。这引发了对LoRA在程序准确性和理解至关重要的场景中适用性的担忧。
Recent research has highlighted the limitations of the Low-Rank Adaptation (LoRA) method in fine-tuning large language models, particularly in the context of multi-step procedural knowledge. The study found that LoRA consistently underperformed compared to traditional full fine-tuning methods, especially in tasks that require a deep understanding of complex procedures. This raises concerns about the applicability of LoRA in scenarios where procedural accuracy and comprehension are critical.

Procedural Knowledge Is Not Low-Rank: Why LoRA Fails to Internalize Multi-Step ProceduresThe study reveals that LoRA, a parameter-efficient fine-tuning method for large language models, fails to effectively internalize multi-step procedural knowledge compared to full fine-tuning. In various tasks, LoRA consistently underperformed, particularly in complex procedures, indicating a significant limitation for applications requiring procedural understanding.
