一种设计的卷积神经网络用于图像特征的快速提取，并可以根据环境自行选择是否使用GPU-Design of a convolution neural networks for image feature extraction fast, and you can choose whether to use the GPU itself according to the environment

使用tensorflow实现几类深度学习，如卷积神经网络、自回归神经网络、动态神经网络等-Use tensorflow to achieve several kinds of deep learning, such as convolution neural network, recurrent neural network, dynamic neural network
