Transfer from http://blog.csdn.net/zouxy09/article/details/8781543CNNs is the first learning algorithm to truly successfully train a multi-layered network structure. It uses spatial relationships to reduce the number of parameters that need to be learned to improve the training performance of the general Feedforward BP algorithm. In CNN, a small part of the image (local sensing area) as the lowest layer of the input of the hierarchy, the information is transferred to different layers, each layer

Motive (motivation)For non-linear classification problems, if multiple linear regression is used to classify, it is necessary to construct many high-order items, which leads to too many learning parameters, so the complexity is too high.Neural networks (Neural network)As shown in a simple neural network, each circle represents a neuron, each neuron receives the output of the previous neuron as its input, wh

a summary of neural networks found that now every day to see things have a new understanding, but also to the knowledge of the past. Before listening to some of Zhang Yuhong's lessons, today I went to see some of his in-depth study series in the cloud-dwelling community, it introduces the development of neural network history, the teacher is very humorous, theory a lot, no matter what anyway can say a 123,

Now that the "neural network" and "Deep neural network" are mentioned, there is no difference between the two, the neural network can not be "deep"? Our usual logistic regression can be thought of as a neural network with sigmoid (logistic) for output layer activation functions without hidden layers, and it is clear th

Over the past few days, I have read some peripheral materials around the paper a neural probability language model, such as Neural Networks and gradient descent algorithms. Then I have extended my understanding of linear algebra, probability theory, and derivation. In general, I learned a lot. Below are some notes. I,Neural Network I have heard of

The biggest problem with full-attached neural networks (Fully connected neural network) is that there are too many parameters for the full-connection layer. In addition to slowing down the calculation, it is easy to cause overfitting problems. Therefore, a more reasonable neural network structure is needed to effectively reduce the number of parameters in the

The radial basis function (RBF) method of multivariable interpolation (Powell) was proposed in 1985. 1988 Moody and darken a neural network structure, RBF neural network, which belongs to the Feedforward neural network, can approximate any continuous function with arbitrary precision, especially suitable for solving the classification problem. The structure of RB

(Original address: Wikipedia)Introduction:Pulse Neural Network spiking Neuralnetworks (Snns) is the third generation neural network model, the simulation neuron is closer to reality, besides, the influence of time information is considered. The idea is that neurons in a dynamic neural network are not activated in every iteration of the transmission (whereas in a

The last time I wrote this note was a 13 thing ... At that time, busy internship, looking for work, graduation and so on did not write down, and now work for half a year is also stable, I will continue to write this note. In fact, a lot of chapters have been read, but have not written out, first from the 5th chapter, 第2-4 Chapter comparison basis, and then fill!5th Chapter Neural NetworksIn chapters 3rd and 4th, we have learned about linear regression

P1038 neural network and p1038 Neural NetworkBackground Artificial Neural Network (Artificial Neural Network) is a new computing system with self-learning ability. It is widely used in many fields such as pattern recognition, function approximation, and loan risk assessment. The Study of

Building your Deep neural network:step by step Welcome to your Week 4 assignment (Part 1 of 2)! You are have previously trained a 2-layer neural network (with a single hidden layer). This week is a deep neural network with as many layers In this notebook, you'll implement the functions required to build a deep neural.

really simple, very mathematical beauty. Of course, as a popular science books, it will not tell you how harmful this method is.Implementation, you can use the following two algorithms:①KMP: Put $w_{i}$, $W _{i-1}$ two words together, run once the text string.②ac automaton: Same stitching, but pre-spell all the pattern string, input AC automaton, just run once text string.But if you are an ACM player, you should have a deep understanding of the AC automaton, which is simply a memory killer.The

Just entered the lab and was called to see CNN. Read some of the predecessors of the blog and paper, learned a lot of things, but I think some blog there are some errors, I try to correct here, but also added their own thinking and deduction. After all, the theory of CNN has been put forward, I just want to be able to objectively describe it. If you feel that there is something wrong with this article, be sure to tell me in the comments below.convolutional n
