Neural network

A neural network is a computer program built from many simple units, loosely modeled on brain cells, arranged in layers. Each unit takes numbers in, multiplies them by adjustable values called weights, adds them up and passes the result on. Training means adjusting millions or billions of weights until the network's outputs match examples, such as labeling photos correctly.

Why it comes up

Hinton, Bengio and LeCun kept working on neural networks through the 1990s and early 2000s, when most of the field had written them off, and nearly every system discussed on this site is one.
