Open source Artificial Neural Network Computing Library FANN Learning Note 1These days machine learning is very fire, neural network is the machine learning algorithm is a more important one. This time I also took some effort, learned a little fur, by the way to do some stud

Pybrain is a well-known Python neural network library, today I used it to do an experiment, referring to this blog, thanks to the original author, gave a specific implementation, the code can be directly copied to run.Our main problems are as follows:First we give a function to construct the dataset that is required to generate this problem . Def generate_data (

Building your Deep neural network:step by step Welcome to your Week 4 assignment (Part 1 of 2)! You are have previously trained a 2-layer neural network (with a single hidden layer). This week is a deep neural network with as many layers In this notebook, you'll implement t

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

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

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

However, there are few learning materials related to Rnns online, so this series is to introduce the principle of rnns and how to achieve i
