活动简介: Recurrent event refers to the situation where an event happens again within a specific time interval after the initial occurrence. In the real world, recurrent events can represent failure of system, internet security breach, etc. To alleviate severe consequences of recurrent event, it is crucial to proactively predict its risk. Such prediction is challenging because the evolution of events, also called trajectory, is dynamic and complex. The state-of-the-art studies apply statistical models that assume homogeneity among all observations and use static predictors in a period, failing to consider each observation’s heterogeneous trajectory. Our approach – TADEL (Trajectory-Based Deep Learning) – is motivated to tackle the problem with the existing approaches by capturing various trajectories and accounting for observation heterogeneity.
