# LoRA的盲区：无法学会多步骤程序性知识

arXiv新论文揭示，LoRA等参数高效微调方法在指令遵循、风格迁移和事实适应等任务上表现出色，但在内化“程序性知识”（即多步骤操作流程）方面存在根本性缺陷。研究发现，程序性知识具有非低秩特性，而LoRA的线性低秩假设无法捕获这种结构。该发现解释了为什么微调模型在处理复杂多步任务时表现不稳定。

**Procedural Knowledge Is Not Low-Rank: Why LoRA Fails to Internalize Multi-Step Procedures**

A new arXiv paper shows that LoRA and similar parameter-efficient fine-tuning methods fail to internalize procedural knowledge—multi-step procedures. The study finds procedural knowledge is not low-rank, so LoRA's core assumption breaks down. This explains why fine-tuned models often struggle with complex sequential tasks.
