English(EN) Bridging the EHR Divide: Asymmetric Contrastive Learning for Cross-National Medical Representation Transfer

新的对比学习方法改进了跨国电子健康记录数据迁移

研究人员开发了一种名为不对称监督对比学习(Asymmetric SupCon)的新预训练目标,以改进电子健康记录(EHR)表征在不同国家医疗系统之间的迁移能力。该方法侧重于对具有积极结果的患者进行聚类,而不明确对阴性患者进行分组,从而解决了临床数据的异质性问题。在大型台湾EHR数据集上预训练时间Transformer编码器,并将其迁移到MIMIC-IV和EHRSHOT等美国数据集上,证明了性能的显著提升,尤其是在疾病预测的少样本学习场景中。 AI

影响 这项研究可能促成更有效的跨境医疗数据协作和分析,从而加速医学研究并改善全球患者护理。
