ideas. In short, the neural network contains several major elements: neuronal nodes, layers (layer), weights (weights) and biases (bias). The two computational processes of neural networks are forward propagation and reverse propagation respectively. The forward propagation of each layer contains the weighted sum (convolution) respectively. The linear operation

Neural network and deep learning article One: Using neural networks to recognize handwritten numbers

computer programs to learn and recognize handwritten numbers. Although this program is only 74 lines, and does not use any special neural network library, but it can be without any human intervention, to achieve more than 96 of the handwritten digit recognition accuracy rate. In the following chapters, we will further refine our approach to achieve an accuracy r

Implementation of three kinds of cyclic neural network (RNN) algorithm (from scratch, Theano, Keras) _ Neural network

network, to understand DBN and SAE is necessary, I also have to take time to learn CNN, there are times to finish this article, add point description text. In addition, do not start directly with Keras these packaged libraries, but first to understand the RNN bottom of the principle and calculation formula, so that RNN can grasp more thoroughly. And these packaging libraries are not omnipotent, when the model is more complex, some functions through t
