Web1. Algorithm Description BP The neural network is a multi -layer network with an input layer, one or more hidden layers, and an output layer. Each neuron on the implicit layer and the output layer corresponds to a stimulating function and a threshold. The neurons on each layer are connected to the neurons on the adjacent layer through weight.
