WebApr 3, 2024 · Dynamic-DeepHit learns the time-to-event distributions without the need to make any assumptions about the underlying stochastic models for the longitudinal and … WebAffine Maps. One of the core workhorses of deep learning is the affine map, which is a function f (x) f (x) where. f (x) = Ax + b f (x) = Ax+b. for a matrix A A and vectors x, b x,b. The parameters to be learned here are A A and b b. Often, b b is refered to as the bias term. PyTorch and most other deep learning frameworks do things a little ...
