hello, I use to DeepRecurrentSurvivalMachines to model the staying length in ICU, the parameter of shape and scale become NaN after the first back propagation. how to deal with input data?

chiragnagpal commented 1 year ago

are you sure there are no nans in the input or the labels?

JiangWatson commented 1 year ago

Thanks for your reply! I have fixed the problem. There is a zero value in survival time.
