Abstract
A computer-implemented process for training a prediction model for survival analysis includes the following operations. A batch of data is elected from a training dataset representing a plurality of individuals. A curve representing a survival rate of a group of individuals within the batch over a period of time is generated using a non-parametric statistical function and for the batch of data. Individual survival functions for each individual within the batch are estimated using the prediction model. An average survival function is generated from the individual survival functions. A calibration loss is generated using the curve representing the survival rate and the average survival function. Weight of a neural network including the prediction model are updated based upon a total loss including the calibration loss.
