WebAug 12, 2024 · DeepHit. DeepHit is a deep learning model adapted to survival (time-to-event) analyses. It can be modified for use investigating single risks or competing risks. Since this is a discrete-time model, the first step in our investigation is to define discrete times to evaluate.. There are two ways we can approach this.
