perceptron neural network

I ask Xi Xi, a few days ago to play with a bit of MATLAB in the use of Neural network toolbox, and suddenly there is "palpable" the sense of the well-being. The other is nothing, but the data structure of the neural network is a bit "weird", if careless will cause the toolbox error. Here is the correct open posture for

Overview This demo is very suitable for beginners AI and deep learning students, from the most basic knowledge, as long as there is a little bit of advanced mathematics, statistics, matrix of relevant knowledge, I believe you can see clearly. The program is written without the use of any third-party deep Learning Library, starting at the bottom. First, this paper introduces what is neural network, the chara

This article is the source code of their own reading a bit of summary. Please specify the source for the transfer.Welcome to communicate with you. qq:1037701636 Email:[email protected]Written in front of the gossip:Self-feeling should not be a very good at learning the algorithm of people. The past one months have been due to the need to contact the BP neural network. Until now, I have always felt that the

The 1th chapter introduces the course of deep learning, mainly introduces the application category of deep learning, the demand of talents and the main algorithms. This paper introduces the course chapters, the course arrangement, the applicable crowd, the prerequisites and the degree to be achieved after the completion of the study, so that students have a basic understanding of the course. The 2nd chapter of Neural

These two days in the study of artificial neural networks, using the traditional neural network structure made a small project to identify handwritten numbers as practiced hand. A bit of harvest and thinking, want to share with you, welcome advice, common progress.The usual BP neural

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

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

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

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

A course of recurrent neural Network (1)-RNN Introduction source:http://www.wildml.com/2015/09/recurrent-neural-networks-tutorial-part-1-introduction-to-rnns/ As a popular model, recurrent neural Network (Rnns) has shown great application prospect in NLP. Despite the recent

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

Neural network and deep learning the book has been read several times, but each time there will be a different harvest.The paper of DL field is changing rapidly. There's a lot of new idea coming out every day, I think. In-depth reading of classic books and paper, you will be able to find Remian open problems. So there's a different perspective.Ps:blog is a summary of important contents in the main extract b
