Use a neural network to create a page that responds to a search keyword
For a search engine, each user can click only a search result, instead of other content, to provide the engine with information about his or her preferences for the search results in a timely manner.
Therefore, we can construct a neural network to provide the network with the words to be queried, the search results returned to users
The fourth lecture of Professor Geoffery Hinton's Neuron Networks for machine learning mainly describes how to use the back propagation algorithm to learn the characteristic representation of a vocabulary.Learning to predict the next wordThe next few sections focus on how to use the back propagation algorithm to learn the feature representation of a vocabulary. Starting with a very simple example, we introduce the use of the back propagation algorithm to convert the relevant information between

Artificial neural Network (ANN) is a mathematical model for information processing, which is similar to the structure of synaptic connection in the brain, in which a large number of nodes (or neurons) are connected to form a network, that is, "neural network", in order to achieve the purpose of processing messages, neural networks usually need to be trained, Trai
Recently has been looking at convolutional neural network, want to improve the improvement to make something new, read a lot of papers, wrote a review of Deep learning convolutional neural Network has some new understanding, and share with you.In fact, convolutional neural network is not a new algorithm, as early as the 80 's has been proposed, but the hardware i

This article will focus on the fourth week of teacher Wunda's video content and notes, showing some important convolution neural netw
This chapter does not involve too many neural network principles, but focuses on how to use the Torch7 neural networkFirst require (equivalent to the C language include) NN packet, the packet is a dependency of the neural network, remember to add ";" at the end of the statement, this is the same as MATLAB will print out the data. Torch allows us to design our own

Currently, Java is used to develop the largest number of ape programs, but most of them are limited to years of development. In fact, Java can do more and more powerful!
I used Java to build a [self-built neural network] instead of laboratory work, it is a real, direct application that makes our programs smarter, let our program have the perception or cognitive function! Do not use the same number as the neural
Abstract: With the development of computational intelligence, artificial neural network has been developed. The industry now considers that it may not be appropriate to classify neural networks (NN) in artificial intelligence (AI), and that the classification of computational Intelligence (CI) can explain the nature of the problem. Some topics in evolutionary computing, artificial life and fuzzy logic syste
The article was transferred from the deep learning public numberDeep learning is a new field in machine learning that is motivated by the establishment and simulation of a neural network for analytical learning of the human brain, which mimics the mechanisms of the human brain to interpret data, examples, sounds and texts. Deep learning is a kind of unsupervised learning.The concept of deep learning derives from the research of artificial
In the first two sections, the logistic regression and classification algorithms were introduced, and the linear and nonlinear data sets were classified experimentally. Logistic uses a method of summation of vector weights to map, so it is only good for linear classification problem (experiment can be seen), its model is as follows (the detailed introduction can be viewed two times blog:
linear and nonlinear experiments on logistic classification of machine learning (continued)):
That being the
4 activation function
One of the things to be concerned about when building a neural network is what kind of activation function should be used in each separate layer. In logistic regression, the sigmoid function is always used as the activation function, and there are some better choices.
The expression for the tanh function (hyperbolic Tangent function, hyperbolic tangent) is:
The function image is:
The Tanh function is actually a shifted version
1. Recurrent neural Network (RNN)
Although the expansion from the multilayer perceptron (MLP) to the cyclic Neural network (RNN) seems trivial, it has far-reaching implications for sequence learning. The use of cyclic neural networks (RNN) is used to process sequence data. In the traditional neural network model, the

The accuracy of the mnist test set is about 90% and 96%, respectively, for single-layer neural networks and multilayer neural networks in the previous two essays. The correct rate has been greatly improved after the multi-layer neural network has been swapped. This time the convolutional neural network will be used to
Basic types and learning algorithms for neural networks:At present, there are dozens of kinds of neural network models, which can be classified into three categories according to network structure : Feedforward Network, feedback network and self-organizing network .feedforward Neural network refers to the hierarchical arrangement of neurons, which are composed of
