x

Gradient Step on X: "A function takes input, gives output. Example: f(x) = 2x + 3. Simple as that."

Composition: feed one function's output into another. f(g(x)) means apply g first, then f. Example: g(3)=9, then f(9)=21. A 3-layer neural net is literally f3(f2(f1(x))). Each layer is a function ...
