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 blog will introduce a neural network algorithm package in R: Neuralnet, which simulates a set of data, shows how it is used in R, and how it is trained and predicted. Before introducing Neuranet, let's briefly introduce the neural network algorithm .Artificial neural
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
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
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
What is an activation function
When biologists study the working mechanism of neurons in the brain, it is found that if a neuron starts working, the neuron is a state of activation, and I think that's probably why a cell in the neural network model is called an activation function.So what is an activation function, and we can begin to understand it from the logistic regression model, the following figure i
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 ac
BP (Back Propagation)The network was proposed by a team of scientists headed by Rumelhart and mccelland in 1986. It is a multi-layer feed-forward Network trained by the error inverse propagation algorithm and is one of the most widely used neural network models. The BP network

Neural network and deep learning the book has been read several times, but each time there will be a different harvest. DL field of paper, every day there will be a lot of new idea out, I think, in-depth reading classic books and paper, must be able to find Remian open problems, so there is a different perspective.Ps:blog is a summary of important contents in the main extract book.Summary section

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 com

In the last article, we introduce the basic model of BP neural network, some terms in the model and the mathematical analysis of the model, and have a preliminary understanding of its principle. Then how to use the program language to specifically implement it, will be the next issue we need to discuss. This paper chooses the C language to
Artificial neural network is a simulation of the biological nervous system. Its information processing function is determined by the input and output characteristics (activation characteristics) of the network Unit (neuron), the topology of the network (the connection mode of the neuron), the connection weight (synapti
