This might make some sense if DNNs were being used to further our understanding of theoretical physics, but afaik they’re not. They’re being used to classify cat pics. SInce when do you use polynomial Hamiltonians to recognise cats?
These properties mean that neural networks do not need to approximate an infinitude of possible mathematical functions but only a tiny subset of the simplest ones
No finite DNN can approximate sin(x) over the entire real numbers, unless you cheat by having a sin(x) activation function.
