16. Appendix: Mathematics for Deep Learning -- Dive into Deep Learning 0.7 documentation

One of the wonderful parts of modern deep learning is the fact that much of it can be understood and used without a full understanding of the mathematics below it. This is a sign of the fact that the field is becoming more mature. Most software developers no longer need to worry about the theory of computable functions, or if programming languages without a goto can emulate programming languages with a goto with at most constant overhead, and neither should the deep learning practitioner need to worry about the theoretical foundations maximum likelihood learning, if one can find an architecture to approximate a target function to an arbitrary degree of accuracy. That said, we are not quite there yet. Sometimes when building a model in practice you will need to understand how architectural choices influence gradient flow, or what assumptions you are making by training with a certain loss function.
