Code principle: training data extraction and normalization of data, four characteristics of four kinds of signals signal matrix is loaded into a matrix, randomly extracted 1500 samples for training samples, 500 samples for sample. Initialization of weights training, the network, the network predicted output, output in the hidden layer, output output, weighting threshold correction calculation error, calculate the rate of weight change, feature classification, output in the hidden layer,
Analysis of results, according to the network output to identify the data belong to which class, draw the projected types and the actual classification of types of diagram, shows the correct rate.
