Time-Aware Context-Gated Graph Attention Network for Clinical Risk Prediction

要点总结: 1

已有的方法通常过于关注时间特征或临床事件变量的内在关系,或者分两个阶段提取这些信息,导致患者的特征信息不足,从而降低预测性能。

基于异构图神经网络的现有方法通常需要手动选择元路径,这是一个缺点。

为解决上述问题,提出了一个新的模型:时间感知上下文门控图注意网络(Time-Aware Context-Gated Graph Attention Network, T-ConextGGAN)。

T-ConextGGAN包含一个具有时间感知元路径和自我注意机制的图神经网络(GNN)模块,能够同时提取EHR数据的时间语义信息和内在关系,并自动选择元路径。

通过使用来自两个开源数据集的第一次ICU入院的前48小时的EHR数据,对该模型进行了评估,同时对EHR图上的各种临床变量进行了建模。

大量的实验结果表明,T-ConextGGAN能够有效地提取信息特征,并在多个预测指标上优于现有的先进模型。
