Neural networks

(Artificial) neural networks are a type of machine learning model inspired by biological networks in mammalian brains. These networks of neurons (hence, neural networks) process information by composing trillions of simple computations into massively-connected networks which are capable of performing all kinds of difficult tasks. Artificial neural networks are highly simplified when compared to their biological forebears, but the underlying principle of composing simple computations to produce intelligent results is the same (see deep learning, deep neural networks).
