Backpropagation
Short for "backward propagation of errors." The algorithm that computes the gradient of the loss function with respect to every weight in a multi-layer network, by applying the chain rule backwards from the output layer to the input layer.

The algorithm that computes the gradient for every weight efficiently. Done automatically by frameworks. (M03)
