A4.3.8 Artificial Neural Networks (ANNs)
An artificial neural network takes its design from the brain. It is built from many simple units, called neurons, wired together so that data flows through them and the network learns patterns from examples rather than from fixed rules. This page outlines what an ANN is and what it does, sketches the single neuron (the perceptron) and its parts, and sketches how those neurons are stacked into layers in a multi-layer...
