传统中医(TCM)需要精确辨证、确定治则和处方,依赖数十年临床经验。尽管已有基于TCM的决策系统及机器学习研究,但数据限制和单目标约束阻碍实际应用。大语言模型(LLM)在复杂任务中展现潜力,但在TCM领域缺乏专业化,且面临模型过大难以部署和幻觉问题。
研究者推出Tianyi——一个76亿参数的LLM,专为TCM设计。通过渐进式学习方式,在包括经典文本、专家论著、临床记录和知识图谱的多样化TCM语料上进行预训练和微调,旨在吸收互联且系统的TCM知识,适应实际临床需求。
建立TCMEval综合评估基准,用于在TCM考试、临床任务、领域特定问答和实际试验中评估LLM。广泛评估显示,Tianyi作为AI助手在TCM临床实践和研究中具有显著潜力,弥合了TCM知识与实际应用之间的差距。
Natural medicines, particularly Traditional Chinese Medicine (TCM), are gaining global recognition for their therapeutic potential in addressing human symptoms and diseases. TCM, with its systematic theories and extensive practical experience, provides abundant resources for healthcare. However, the effective application of TCM requires precise syndrome diagnosis, determination of treatment principles, and prescription formulation, which demand decades of clinical expertise. Despite advancements in TCM-based decision systems, machine learning, and deep learning research, limitations in data and single-objective constraints hinder their practical application. In recent years, large language models (LLMs) have demonstrated potential in complex tasks, but lack specialization in TCM and face significant challenges, such as too big model scale to deploy and issues with hallucination. To address these challenges, we introduce Tianyi with 7.6-billion-parameter LLM, a model scale proper and specifically designed for TCM, pre-trained and fine-tuned on diverse TCM corpora, including classical texts, expert treatises, clinical records, and knowledge graphs. Tianyi is designed to assimilate interconnected and systematic TCM knowledge through a progressive learning manner. Additionally, we establish TCMEval, a comprehensive evaluation benchmark, to assess LLMs in TCM examinations, clinical tasks, domain-specific question-answering, and real-world trials. The extensive evaluations demonstrate the significant potential of Tianyi as an AI assistant in TCM clinical practice and research, bridging the gap between TCM knowledge and practical application.
