=== Artificial neural networks ===
{{Main|Artificial neural network}}An artificial neural network (ANN) is based on a collection of connected units or nodes called [[artificial neuron]]s, which loosely model the [[neuron]]s in a biological [[brain]]. Each connection, like the [[synapse]]s in a biological [[brain]], can transmit a signal from one artificial neuron to another. An artificial neuron that receives a signal can process it and then signal additional artificial neurons connected to it. In common ANN implementations, the signal at a connection between artificial neurons is a [[real number]], and the output of each artificial neuron is computed by some non-linear function of the sum of its inputs.{{citation needed|date=December 2018}}
