摘要:

针对特定任务高效微调大语言模型(LLM)是自然语言处理领域的一大挑战。提示调优或前缀调优等传统方法通常依赖任意token进行训练,导致训练时间过长,且各类别标签共用通用token。为解决这些问题,本文提出L-Tuning,这是一种专为自然语言推理(NLI)框架下的分类任务设计的高效微调方法。与传统方法不同,L-Tuning聚焦于对经预训练LLM处理的标签token进行微调,从而利用模型已有的语义知识。该技术不仅提升了微调的准确率与效率,还能为每个类别生成差异化的标签嵌入,增强模型训练的精细度。实验结果表明,与传统方法相比,L-Tuning在训练效率和分类准确率上均有显著提升,为面向复杂语言任务的LLM微调研究带来了颇具前景的进展。

英文摘要:

Efficiently fine-tuning Large Language Models (LLMs) for specific tasks presents a considerable challenge in natural language processing. Traditional methods, like prompt or prefix tuning, typically rely on arbitrary tokens for training, leading to prolonged training times and generalized token use across various class labels. To address these issues, this paper introduces L-Tuning, an efficient fine-tuning approach designed for classification tasks within the Natural Language Inference (NLI) framework. Diverging from conventional methods, L-Tuning focuses on the fine-tuning of label tokens processed through a pre-trained LLM, thereby harnessing its pre-existing semantic knowledge. This technique not only improves the fine-tuning accuracy and efficiency but also facilitates the generation of distinct label embeddings for each class, enhancing the model's training nuance. Our experimental results indicate a significant improvement in training efficiency and classification accuracy with L-Tuning compared to traditional approaches, marking a promising advancement in fine-tuning LLMs for complex language tasks.
