利用Python实现的BP神经网络进行人脸识别
实现的BP神经网络为典型的三层神经网络
#定义 #nInput : Number of Neuron in input layer #nHide : Number of Neuron in hide layer #nOutput : Number of Neuron in output layer #studyspeed ： Learning Rate network = NeuralNetWork(nInput = nInput , nHide = nHide,nOutput = nOutput,studyspeed = 0.05)
#训练过程 #Training with single example #training : [input0,input1,input2...] #example : [output0,output1,output2...] (excepted output) network.backpropagationSingle(training = training,example = example)
#使用 #Get the output of network when the input is inputTest res = network.getOutput(inputTest)
