The contemporary paradigm of trajectory learning operates fundamentally at the level of group dynamics, systematically reducing individual-level complexity to fit group-level models, thus rendering effective patient subtyping difficult and individual-level modeling largely out of reach. We propose a data-driven paradigm that introduces a dedicated individual-level temporal variable to capture \emph{Timing Attention} (i.e., the degree of concentration of an event's timing distribution across the patient cohort), thereby rendering timing a \emph{computable dimension} that enables individualized temporal features in trajectory learning.
Instantiated as the Level-of-Individual Time Transformation (LITT) and applied to longitudinal EHR data from 3,276 breast cancer patients, the proposed paradigm demonstrates, for the first time to our knowledge: (1) automatic discovery of clinically significant patient trajectories, and (2) counterfactual timing deduction, that is, a \emph{What-If Machine}. Both results are purely data-driven, requiring no prior domain knowledge. LITT further achieves strong performance on timing prediction and survival analysis tasks.

Early Prediction of Sepsis From Clinical Datavia Heterogeneous Event Aggregation

脓毒症是一种危及生命的疾病,严重危及全世界数百万人的生命。随着电子健康记录(EHR)的广泛应用,可以有效处理临床序列数据的预测模型有望增加预测脓毒症并采取早期预防治疗的可能性。然而,早期预测是具有挑战性的,因为患者的序列数据在EHR中包含多个临床事件的时间相互作用。传统的LSTM很难捕捉长事件序列中的时间交互。我们提出的模型不是直接将LSTM模型应用于事件序列,而是首先在短时间内聚合异构临床事件,然后捕获聚合表示与LSTM的时间交互。我们提出的异构事件聚合不仅可以缩短临床事件序列的长度,而且还有助于在聚合表示的多个头部中保留临床事件的分类和数值特征的时间交互。在PhysioNet/Computing in Cardiology Challenge 2019中,与名为PKU_DLIB的团队合作,我们提出的模型在全测试集中以高效率获得了效用得分(0.321)。
