Turn from: The Heart of the machine Introduction Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult. Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations and manually perform these steps (and calcula

The basic knowledge of neural network can refer to the basic knowledge of neural network, the basic thing is very good, and then the solution of the parameters in the neural network is explained. Some variables are explained: Th
Preface I have been dealing with neural networks (ANN) for a long time. I used to learn the principles. I have done a BPN exercise. I have not summarized it systematically. I recently read the torch source code, I have a better understanding of MLP, and I have made a summary by writing what I learned!Features of ANN (1) high concurrency Artificial Neural Networks are made up of many parallel combinations of

The Microsoft Neural Network is by far the most powerful and complex algorithm. To find out how complex it is, look at the SQL Server Books Online description of the algorithm: "This algorithm establishes a classification and regression mining model by establishing a multi-layered perceptual neuron network." Similar to the Microsoft Decision tree algorithm, when
BP Neural Network is a multi-layer feedforward neural network which is trained according to the error inverse propagation algorithm, and is the most widely used neural network at present.BP ne
The contents of this article for I learn to understand, there is wrong place also please point out. The so-called BP neural Network (back propagation) is to use the known data set along the neural network forward to calculate the predicted value, so as to obtain the deviation between the predicted value and the actua
ICML 2016 's article [Noisy Activation Functions] gives the definition of an activation function: The activation function is a map h:r→r and is almost everywhere.The main function of the activation function in neural network is to provide the nonlinear modeling ability of the network, if not specifically, the activation function is generally nonlinear function. A
At present, there are neural networks in all aspects of engineering application, and younger brother is now learning neural network, a little conjecture.Most of the current neural network is to adjust their own weights, so as to learn. Under the structure of a certain
Origin: Linear neural network and single layer PerceptronAn ancient linear neural network, using a single-layer Rosenblatt Perceptron. The Perceptron model is no longer in use, but you can see its improved version: Logistic regression.You can see this network, the input-weig
Recently, the journal Platform Distill published an article by Google researchers, introducing a powerful tool for neural network visualization and style migration: micro-image parameterization. This article describes the tool in several ways. Image Classification Neural network has excellent image generation capa
Hopfield Neural network usage instructions.There are two characteristics of this neural network:1, output value is only 0, 12,hopfield not entered (input)Here's a second feature, what do you mean no input? Because in the use of Hopfield network, more used for image simulatio
After figuring out the fundamentals of convolutional Neural Networks (CNN), in this post we will discuss the algorithm implementation techniques based on Theano. We will also use mnist handwritten numeral recognition as an example to create a convolutional neural network (CNN) to train the network so that the recogniti
Why should I introduce an activation function?If you don't have to activate the function (actually equivalent to the excitation function is f (x) =x), in this case you each layer of output is a linear function of the upper input, it is easy to verify that no matter how many layers of your neural network, the output is a linear combination of input, and no hidden layer effect, this is the most primitive perc
This paper, based on the http://en.wikipedia.org/wiki/Backpropagation of Wikipedia, makes a summary of the neural network's back propagation algorithm, and makes a simple formula derivation.A typical post-propagation algorithm for a 3-layer neural network with only 1 hidden layers is as follows:Initialize network weigh

From sensor to Neural Network Perception Machine The sensor was invented by science and technology Frank Rosenblatt in and was influenced by Warren McCulloch and Walter Pitts's early work. Today, the use of other Artificial Neuron models is more common-in this book, and more modern neural networks work, primarily using a neuron model called S-type neurons. How
