bp neural network in BP for back propagation shorthand, the earliest it was by Rumelhart, McCelland and other scientists in 1986, Rumelhart and in nature published a very famous article "Learning R Epresentations by back-propagating errors ". With the migration of the Times, the theory of BP neural network has been imp

1 What is a neural networkArtificial Neural Networks (Artificial Neural Networks, abbreviated as Anns) are also referred to as neural networks (NNs) or as connection models (Connection model), which mimic the behavior characteristics of animal neural networks, The mathematic

Reference booksDeep learningDeep learning is a new field in machine learning research, and its motive is to establish and simulate the neural network of human brain import analysis and learning, which imitates the mechanism of human brain to interpret the data.Examples of images, sounds and text. Deep Learning is a kind of unsupervised learning. The concept of deep learning is derived from the research o

Convolution Neural network Convnets is used to process data with multiple array formats, such as a color image consisting of three two-dimensional arrays, which contains pixel intensities on three color channels. Many data forms are in the form of multiple arrays: one-dimensional signals and sequences, including languages; Two-dimensional image or audio spectrum, three-dimensional video or stereo image. Co

Machine Learning:neural NetworkA: PrefaceDefinition of the neural network on 1,wikipedia:InchMachine Learning, Artificial neural networks (anns) is a family of statistical learning algorithms inspired byBiological Neural Networks(TheCentral Nervous Systemsof animals, in particular theBrain) and is used to estimate orap

reversal of the convolutional neural network. For example, enter the word "cat" to train the network by comparing the images generated by the network with the real images of the cat, so that the network can produce images more like the cat. DN can be combined with ffnn like

Objectivethe first article of the 2017.10.2 Blog Park, Mark. Since the lab was doing NLP and medical-related content, it began to gnaw on the nut of NLP, hoping to learn something. Follow-up will focus on knowledge map, deep reinforcement learning and other content.To get to the point, this article is a introduciton of using neural networks to deal with NLP problems. Hopefully, this article will have a basic concept of natural language processing (usi

The construction of Neural Networks (neural network) is inspired by the operation of biological neural network function. Artificial neural networks are usually optimized by a learning method based on mathematical statistics, so ar

PHP is really a headache, you can't understand it, you can't get it from the boss. you can help me to see what PHP is for the blockchain network code. it's really a headache, you can't understand it, you can't get it from the boss. Let me see what the code is. , These CMS are actually server-oriented. a single file writes some code, and there are fewer. a single file sets a variable. All the indexes on

TensorFlow implements RNN Recurrent Neural Network, tensorflowrnn RNN (recurrent neural Network) recurrent neural Network It is mainly used for natural language processing (NLP) RNN is mainly usedProcess and predict sequence data

Learning/Training Algorithm classification The different types of neural networks correspond to different kinds of training/learning algorithms. Therefore, according to the classification of neural networks, the traditional neural network learning algorithms can be divided into the following three categories: 1 feedfor

gap. In the comprehensive evaluation of customer service perception of information system, it involves a lot of complex phenomena and the interaction of many factors, moreover, there are a lot of fuzzy phenomena and fuzzy concepts in the evaluation. Therefore, in the comprehensive evaluation, some scholars use the method of fuzzy comprehensive evaluation to quantify, evaluate the information System customer service awareness level, and has achieved some results. However, using this method to mo

Summary:On March 13, 2018, the Shen Junan community, from Harbin Institute of Technology, shared a typical model-an introduction to deep neural networks. This paper introduces the development course of deep neural network in detail, and introduces the structure and characteristics of each stage model in detail.The Shen Junan of Harbin Institute of Technology shar

1. Data preprocessingbefore training the neural network, it is necessary to preprocess the data, and an important preprocessing method is normalization processing. The following is a brief introduction to the principle and method of normalization processing. (1) What is normalization?Data normalization is the mapping of data to [0,1] or [ -1,1] intervals or smaller intervals, such as (0.1,0.9).(2) Why shoul

I. Artificial neural element model1. Synaptic value (connection right)Each synapse is characterized by its weight, and the connection strength between each neuron is represented by the synaptic value. On synapses connected to neurons, the connected input signal enters the sum unit of the neuron by weighting the weights. 2. Summation UnitThe summation unit is used to calculate the synaptic weighting of each input signal and this operation forms a linea
