Also called Kohonen Mapping), referred to as the SMO network, is mainly used to solve the problem of pattern recognition class. The SMO network is a unsupervised learning algorithm similar to the previous Kmeans al

End-to-end neural network MT (end-to-end Neural machine translation) is a new method of machine translation emerging in recent years. In this paper, we will briefly introduce the traditional method of statistical machine translation and the application of neural network in machine translation, then introduce the basic coding-decoding framework (Encoder-decoder) i

1 Introduction An XOR operation is a commonly used calculation in a computer: 0 XOR 0 = 0 0 XOR 1 = 1 1 XOR 0 = 1 1 XOR 1 = 0 We can use the code in the first article to calculate this result Http://files.cnblogs.com/gpcuster/ANN1.rar (need to modify the training set), we can find that the results of learning does not satisfy us, because the single layer of neural network learning ability is limited , you need to use more complex networks to lea

"Self-built Neural Networks" is an e-book. It is the first and only Neural Network book on the market that uses Java. What self-built Neural Networks teach you: Understand the principles and various design methods of neural networks, and make it easy to use ground gas; Understand the implementation of each component o

Neural NetworkIt is a system that can adapt to the new environment. It has the ability to analyze, predict, reason, and classify the past experience (information, it is a system that can emulate the human brain to solve complex problems. Compared with conventional systems (using statistical methods, pattern recognition, classification, linear or nonlinear methods, A Neural Network-based system has more powe

The linear neural network is similar to the perceptron, but the activation function of the linear neural network is linear rather than the hard transfer function, so the output of the linear neural network can be any value, and the output of the perceptron is not 0 or 1. Linear neural networks, like Perceptron, can onl

In the deep network, the learning speed of different layers varies greatly. For example: In the back layer of the network learning situation is very good, the front layer often in the training of the stagnation, basically do not study. In the opposite case, the front layer learns well and the back layer stops learning.This is because the gradient descent-based learning algorithm inherently has inherent instability, which causes the learning of the front or back layer to stop.Vanishing gradient p

UFLDL Learning notes and programming Jobs: multi-layer neural Network (Multilayer neural networks + recognition handwriting programming)UFLDL out a new tutorial, feel better than before, from the basics, the system is clear, but also programming practice.In deep learning high-quality group inside listen to some predecessors said, do not delve into other machine learning algorithms, you can directly to learn

"This paper presents a comprehensive overview of the depth of neural network compression methods, mainly divided into parameter pruning and sharing, low rank decomposition, migration/compression convolution filter and knowledge refining, this paper on the performance of each type of methods, related applications, advantages and shortcomings of the original analysis. ” Large-scale neural networks have a la

If you use 100k batch in this model, and combine the decay of learning rate (that is, the rate of learning is reduced by a ratio every once in a while), the correct rate can be as high as 86%. There are about 1 million parameters to be trained in the model, and the total amount of arithmetic to be estimated is about 20 million times. So this convolution neural network model, using some techniques.(1) Regularization of the L2 of the weight.(2) The imag

Artificial neural Network (Artificial neural netwroks) Notes--2.1.3 steps in the discrete multi-output perceptron training algorithm are multiple judgments, so we say it's a discrete multiple output perceptron. Now take the formula Wij=wij+α (YJ-OJ) Xi instead of that step The effect of the difference between Yj and Oj on Wij is manifested by alpha (YJ-OJ) XI The advantage of this is that it not only mak

Http://www.cnblogs.com/python27/p/MachineLearningWeek05.html This chapter may be the most unclear chapter of Andrew Ng, why do you say so? This chapter focuses on the back propagation (backpropagration, BP) algorithm, Ng spent half time talking about how to calculate the error item δ, how to calculate the δ matrix, and how to use MATLAB to achieve the post transmission, but the most critical question-why so calculate. The previous calculation of these amounts represents what, Ng basically did n

I've been watching "neural network Design_hagan" Then you want to implement an XOR network yourself. Because the single layer neural network can not divide the different or the judgment to two kinds. According to a^b= (a~b) | (~AB) And I tried it. Or and with both can be solved with sensory neurons, that is, one. Then with and or by the implementation: Hardlim (n) =a, n>=0 when a=1;n Obviousl

First conclusion: When using sigmoid as activating function, cross entropy has the characteristics of fast convergence and global optimization compared to quadratic cost function. Using Softmax as the activation function, Log-likelihood as a loss function, there is no drawback of slow convergence.For the convergence of the loss function, we expect that when the error is greater, the speed of convergence (learning) should be faster. First, quadratic + sigmoid (i), definition Definitions of squar
