摘要:

电子健康记录(EHR)的广泛采用导致了大量的临床数据变得可用,这有望支持服务提供并推进临床和信息学研究。深度学习技术已经在使用EHR的预测分析任务中表现出性能,但它们通常缺乏模型结果透明度或可解释性功能,并且需要繁琐的预处理任务。此外,EHR包含异构和多模态数据点,如文本,数字和时间序列,这进一步阻碍了可视化和可解释性。本文提出了一个深度学习框架,用于:1)将患者路径从EHR编码到图像中,2)突出路径图像中的重要事件,3)实现更复杂的预测和额外的可理解性。所提出的方法依赖于一个深注意力机制的预测可视化,并允许预测多个连续的结果。

英文摘要:

The wide adoption of Electronic Health Records (EHR) has resulted in large amounts of clinical data becoming available, which promises to support service delivery and advance clinical and informatics research. Deep learning techniques have demonstrated performance in predictive analytic tasks using EHRs yet they typically lack model result transparency or explainability functionalities and require cumbersome pre-processing tasks. Moreover, EHRs contain heterogeneous and multi-modal data points such as text, numbers and time series which further hinder visualisation and interpretability. This paper proposes a deep learning framework to: 1) encode patient pathways from EHRs into images, 2) highlight important events within pathway images, and 3) enable more complex predictions with additional intelligibility. The proposed method relies on a deep attention mechanism for visualisation of the predictions and allows predicting multiple sequential outcomes.
