Recurrent neural network (recurrent neural networks)

programming principle and construct a dynamic sequence model. This requires recurrent neural Network (RNN) to achieve.RNN is usually translated into cyclic neural networks, and its similar dynamic programming principles can also be translated into sequential recurrent neural networks.Of course there are structural rec

"Artificial Neural Network Fundamentals" Why do Neural Networks choose "depth"?

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

Cyclic neural networks (recurrent neural network,rnn)

Why use sequence models (sequence model)? There are two problems with the standard fully connected neural network (fully connected neural network) processing sequence: 1) The input and output layer lengths of the fully connected neural network are fixed, and the input and output of different sequences may have different lengths, Selecting the maximum length and f

convolutional Neural Networks (convolutional neural Network)

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

Neural network Learning (ii) Universal Approximator: Feedforward Neural Networks

$ = 1 (The purpose is to omit the bias entry).Our example here is that the value of the latter layer is determined only by the value of the previous layer, which, of course, is not necessarily a definite one. As long as there is no feedback structure, it can be counted as the forward neural network. So here is the derivation except for a structure called the skip layer, where the current layer is not determined by the previous layer, but by the values

, the objective function of SVM is still convex. Not specifically expanded in this chapter, the seventh chapter is detailed.Another option is to fix the number of base functions in advance, but allow them to adjust their parameters during the training process, which means that the base function can be adjusted. In the field of pattern recognition, the most typical algorithm for this method is the forward neural network (Feed-forward
