Backpropagation

The algorithm that makes neural network training possible.

Definition

The algorithm that makes neural network training possible. It calculates how much each weight in the network contributed to the error, then adjusts them to reduce that error. Works by propagating the error signal backward through the network, layer by layer. The workhorse of deep learning.
