AI总结:

针对深度学习在电子健康记录数据上表现不佳的问题,提出有理逻辑回归(RLR)模型,以标准逻辑回归为特例,基于有理级数理论处理纵向时间序列数据,学习可解释模式,并在真实临床任务中验证其有效性。

摘要:

医疗保健领域近年来积累了大量的数字数据,尤其是以电子健康记录(EHRs)的形式。电子健康记录构成了信息系统(IS)研究人员可用于临床应用(例如,发病率预测)的宝贵资源。深度学习似乎是利用这些丰富数据的显而易见的选择。然而,大量研究表明,深度学习在电子健康记录数据上并未取得与其他领域相同的成功;像逻辑回归这样的简单模型通常与复杂的深度学习模型表现相当。受此观察启发,我们开发了一种名为有理逻辑回归(RLR)的新模型,该模型以标准逻辑回归(LR)作为其特例(因此继承了逻辑回归与电子健康记录数据相契合的归纳偏置)。有理逻辑回归以有理级数为其理论基础,适用于纵向时间序列数据,并能学习可解释的模式。在真实世界临床任务上的实证比较证明了有理逻辑回归的有效性。

英文摘要:

The healthcare sector has experienced a rapid accumulation of digital data recently, especially in the form of electronic health records (EHRs). EHRs constitute a precious resource that IS researchers could utilize for clinical applications (e.g., morbidity prediction). Deep learning seems like the obvious choice to exploit this surfeit of data. However, numerous studies have shown that deep learning does not enjoy the same kind of success on EHR data as it has in other domains; simple models like logistic regression are frequently as good as sophisticated deep learning ones. Inspired by this observation, we develop a novel model called rational logistic regression (RLR) that has standard logistic regression (LR) as its special case (and thus inherits LR's inductive bias that aligns with EHR data). RLR has rational series as its theoretical underpinnings, works on longitudinal time-series data, and learns interpretable patterns. Empirical comparisons on real-world clinical tasks demonstrate RLR's efficacy.
