Function

Internal model

A function is a deterministic relationship between input and output values. Clearly, every machine learning algorithm is in some sense a function, but the word is used here to refer to succinctly writable mathematical relationships as with least squares regression. The term is used as distinct from rules, which form a special class of functions, as well as from more complex structures and programs such as those that make up neural networks.
