Back propagation: the backward propagation of errors or back propagation is a common method of training artificial neural networks and used in conjunction with gradient descent optimization optimization objective of back propagation is the cost function “j.
Thesis of neural network for character classification with backpropagation
Basically, a neural network is just trying to find a function that fits a given set of points if the output is linear, it means that a simple line equation fits your data, which is not the case in the problems we discussed earlier, thus we need the nonlinear property.
