新框架利用时间图和对比学习对疾病轨迹进行建模

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一个新颖的对比表示学习框架，旨在对纵向临床数据中的复杂疾病轨迹进行建模。该方法利用时间图，其中节点代表患者随时间的观察，边捕获轨迹之间的时间和结构关系。通过采用结构感知随机游走和对比图神经网络，该框架生成保留时间上下文和轨迹拓扑的嵌入，从而实现更稳健的患者队列聚类并揭示数据中的潜在结构。 AI

影响 这项研究引入了一种分析复杂健康数据的新方法，有可能改善疾病预测和患者分层。

    Temporal Graphs on Longitudinal Disease Trajectories of Contrastive Representation Learning

    arXiv:2607.25609v1 Announce Type: cross Abstract: Understanding disease trajectories from longitudinal clinical data remains challenging due to complex temporal dynamics and heterogeneous patient cohorts. Here, we present a contrastive representation learning framework that model…
