Application background
Digital recognition is one of the important research directions in pattern recognition, and has broad application prospect.. On the basis of the basic principle of BP neural network,A scheme of handwritten numeral recognition using BP neural network is proposed..Key Technology
The basic idea of BP algorithm is that the learning process consists of two processes: the forward propagation of signal and the error of the error.. Forward propagationThe input sample is passed from the input layer to the output layer after layer by layer.. If the actual output of the output layer and the expected lossThe (teacher's signal) does not match the error, then the back propagation stage of the error.matlab
