摘要:

对高维纵向数据的时间序列进行建模对于预测患者疾病进展非常重要。然而,现有的基于神经网络的学习患者状态的表示的方法虽然非常灵活,但容易过拟合。我们提出了一个深度生成模型,该模型利用了一种新的基于注意力的神经架构,其灵感来自治疗如何影响疾病状态的物理学。结果是高维患者生物标志物的可扩展和准确的模型,因为它们随时间变化。我们提出的模型在泛化方面有了显着的改进,并且在现实世界的临床数据上,为癌症进展的动态提供了可解释的见解。

英文摘要:

Modeling the time-series of high-dimensional, longitudinal data is important for predicting patient disease progression. However, existing neural network based approaches that learn representations of patient state, while very flexible, are susceptible to overfitting. We propose a deep generative model that makes use of a novel attention-based neural architecture inspired by the physics of how treatments affect disease state. The result is a scalable and accurate model of high-dimensional patient biomarkers as they vary over time. Our proposed model yields significant improvements in generalization and, on real-world clinical data, provides interpretable insights into the dynamics of cancer progression.
