训练BP神经网络连接权值的源代码,还可以得到BP的层数和节点数-Training of BP neural network connection weights of the source code, you can also get BP and the number of layers of nodes

基于bp神经网络的人脸识别系统，训练样本大概5000左右可以识别图片中是否有人脸(Face recognition system based on BP neural network)

本代码是一份bp神经网络代码，通过训练、检验、预测，可以实现对网络的完美应用，有需要的同学可以看看。(This code is a BP neural network code, through training, testing, prediction, you can achieve the perfect application of the network, there is a need for students to see.)

实现图像识别，基于小波变换实现图像特征提取，然后神经网络进行训练(The image recognition is realized, the image feature extraction is realized based on wavelet transform, and then the neural network is trained.)
