From entry neural network in glossary Artificial Intelligence: humans at the heart of algorithms
Neural networks algorithms take inspiration from the brain and involve large numers of simple neurons all working together. They are typically organised in layers where the outputs of one layer of neurons form the input to the next, but some neural networks, including Boltzmann machines and Kohonan networks, have connections within layers. Many neural networks are trained using some form of backpropagation.
