This article attempts to invoke it in Python. Same as the previous Bayesian classifier. Neural networks also follow the method of training and re-use, we directly
At the request of a friend wrote a python implementation of the single hidden layer of BP Ann Model code, long time no blog, the way to send up. This code is relatively neat, relatively pure description of the basic principles of Ann, beginners machine learning can refer to students.Some of the more important parameters in the model:1. Learning RateThe learning rate is an important factor that influences the convergence of the model, in general, it sh
Learning means finding a set of weights on the training data to minimize the loss function;
Learning process: Calculates the gradient value of the loss function corresponding to the weight coefficient in the small batch data, then the weight coefficient moves along the gradient in the opposite direction;
The probability of the learning process is based on the neural network is a series of

Let's spit it out. This is based on the Theano Keras how difficult to install, anyway, I am under Windows toss to not, so I installed a dual system. This just feel the powerful Linux system at the beginning, no wonder big companies are using this to do development, sister, who knows ah ....Let's start by introducing the framework: We all know the depth of the neural network,
