English(EN) LoRA vs full fine-tuning: when is LoRA good enough?

LoRA 微调在大多数 LLM 任务上可媲美全量微调

LoRA 微调是许多大型语言模型任务(包括指令和推理数据集)的可行替代全量微调的方法,并且在正确应用时可匹配全量微调的性能。当需要整合大量新知识或数据集大小超出 LoRA 适配器的容量时,全量微调的优势会更加明显。主要区别在于内存需求,全量微调需要显著更多的资源,导致成本更高,并需要更强大的多 GPU 设置。 AI

影响 LoRA 为许多常见任务的 LLM 微调提供了一种更节省内存且更具成本效益的方法。

    LoRA 对比全量微调:何时 LoRA 就足够了?

    <p>LoRA is good enough for most fine-tuning: on normal-sized instruction and reasoning datasets, and in reinforcement learning, it matches full fine-tuning when it covers every layer and uses a higher learning rate. Nodus runs both on its <code>nodus/sft</code> training runtime, …
