English(EN) PaReGTA: A Temporally Aware LLM-Based Patient Representation Framework for EHR Analytics

新的LLM框架PaReGTA增强了来自电子健康记录数据的患者表示

研究人员开发了PaReGTA,一个利用大型语言模型(LLMs)从电子健康记录(EHRs)创建患者表示的新框架。该方法将纵向EHR数据转换为带有时间线索的文本,对领域特定的嵌入进行句子嵌入模型微调,并将这些聚合为固定维度的患者表示。PaReGTA旨在保留传统方法中丢失的时间信息,并在来自“All of Us Research Program”的偏头痛患者的回顾性分类任务中显示出有希望的结果,在AUC、准确率和F1分数方面优于其他方法。 AI

影响 该框架可以提高医疗保健领域患者数据分析的准确性和效率,可能带来更好的诊断工具和个性化治疗方案。

    PaReGTA:一种基于时间感知的LLM的患者表示框架,用于EHR分析

    arXiv:2602.19661v3 Announce Type: replace Abstract: Temporal information in structured electronic health records (EHRs) is often lost in sparse one-hot or count-based representations, while sequence models can be costly and data-hungry. We propose PaReGTA, an LLM-based encoding f…
