Back Propagation is a machine-learning algorithm that trains the weights of connecting nodes on a layered neural network. The application is comprised of two phases: the Forward Phase, in which the activations are propagated from the input to the output layer, and the Backward Phase, in which the error between the observed and requested values in the output layer is propagated backwards to adjust the weights and bias values. In each layer, the processing of all the nodes can be done in parallel.
