摘要:

尽管大型语言模型(LLM)在世界知识理解方面表现出色,但要使其适应特定子领域,仍需进行精确调整。由于模型规模庞大,针对大型模型的传统全局微调方法可能计算成本高昂,并影响泛化能力。为应对这一挑战,一系列创新的参数高效微调(PEFT)方法已经出现,并在LLM和大型视觉-语言模型(LVLM)中取得了显著成功。在医学领域,微调医学视觉-语言预训练(VLP)模型对于使其适应特定任务至关重要。大型模型的微调方法能否迁移到医学领域,以提升迁移学习效率?本文深入研究了LLM的微调方法,并开展大量实验,从训练数据层面和模型结构层面考察大型模型微调方法对医学领域现有多模态模型的影响。我们展示了大型模型微调方法对医学VLM的不同影响,并提出了微调医学VLP模型的最高效方式。我们希望本研究能够指导医学领域研究人员优化VLM的训练成本,推动VLM在医疗健康领域的更广泛应用。代码和数据集已发布于 https://github.com/TIMMY-CHAN/MILE。

英文摘要:

While Large Language Models (LLMs) excel in world knowledge understanding, adapting them to specific subfields requires precise adjustments. Due to the model's vast scale, traditional global fine-tuning methods for large models can be computationally expensive and impact generalization. To address this challenge, a range of innovative Parameters-Efficient Fine-Tuning (PEFT) methods have emerged and achieved remarkable success in both LLMs and Large Vision-Language Models (LVLMs). In the medical domain, fine-tuning a medical Vision-Language Pretrained (VLP) model is essential for adapting it to specific tasks. Can the fine-tuning methods for large models be transferred to the medical field to enhance transfer learning efficiency? In this paper, we delve into the fine-tuning methods of LLMs and conduct extensive experiments to investigate the impact of fine-tuning methods for large models on the existing multimodal model in the medical domain from the training data level and the model structure level. We show the different impacts of fine-tuning methods for large models on medical VLMs and develop the most efficient ways to fine-tune medical VLP models. We hope this research can guide medical domain researchers in optimizing VLMs' training costs, fostering the broader application of VLMs in healthcare fields.
