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

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

The foundation of deep learning--the beginning of neural network Original address fundamentals of Deep learning–starting with Artificial neural network preface Deep learning and neural networks are now driving advances in computer science, both of which have a strong abilit
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
First, what is an artificial neural network? Simply put, a single perceptron as a neural network node, and then use such nodes to form a hierarchical network structure, we call this network is the artificial

Summary of Ann Training algorithm based on traditional neural networkLearning/Training Algorithm classificationThe different types of neural networks correspond to different kinds of training/learning algorithms. Therefore, according to the classification of neural networks, the traditional neural
0-Background This paper introduces the deep convolution neural network based on residual network, residual Networks (resnets).Theoretically, the more neural network layers, the more complex model functions can be represented. CNN can extract the features of low/mid/high-lev
Recurrent neural NetworksIn traditional neural networks, the model does not focus on the processing of the last moment, what information can be used for the next moment, and each time will only focus on the current moment of processing. For example, we want to classify the events that occur at every moment in a movie, and if we know the event information in front of the movie, then it is very easy to classi
Overview This is the last article in a series on machine learning to predict the average temperature, and as a last article, I will use Google's Open source machine learning Framework TensorFlow to build a neural network regression. About the introduction of TensorFlow, installation, Introduction, please Google, here is not to tell. This article I mainly explain several points: Understanding artificial
Tags: des style blog HTTP Io color OS AR I. Artificial Neural Networks Most of the reason why humans can think, learn, and judge is due to the complicated Neural Networks in the human brain. Although the mechanism of the human brain has not yet been completely deciphered, the connection between neurons in the human brain and the transfer of information are all known. So people want to simulate the function
Neural network and support vector machine for deep learningIntroduction: Neural Networks (neural network) and support vector machines (SVM MACHINES,SVM) are the representative methods of statistical learning. It can be thought that neura
This paper summarizes the notes based on the series of machine learning techniques in Taiwan.The main content is as follows:Firstly, the structure of hypothesis and network of radial basis function network is introduced, then the RBF Neural Network learning algorithm is introduced, and the learning by using K-means is
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
