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 n
This document references: http://www.cnblogs.com/tornadomeet/p/3468450.htmlThank you for that.Generally speaking, the output of a multi-class neural network is generally in softmax form, that is, the activation function of the output layer does not use sigmoid or Tanh functions. Then the output of the last layer of the neural

Self-organizing neural network, also known as self-organizing competitive neural network, is especially suitable for solving the problem of pattern classification and recognition. The network model belongs to the Feedforward neural
The author says: Before having studied once, but after a period of time, many details place already blurred. Recently deduced again, in order to retain as far as possible the derivation idea, specially writes this blog post. On the one hand for their future memories, on the other hand to communicate with you to learn.For this blog post, the following description:1. This blog does not guarantee that the derivation process is completely correct, if there is a problem, please correct me.2. If neces

Because the traditional initialization weight problem is randomly initialized with the standard normal distribution (mean 0, Variance is 1), this is actually an unreasonable part. Standard Normal Distribution: It can be seen that the distribution of real data is actually in the part near the peak of the slope, which accords with normal distribution. The following are reproduced Click to open the link Initialization weights in Caffe First n

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 i
Artificial intelligence is not mysterious, will be a little subtraction enough. For neurons, when nerves are stimulated, the neurotransmitter is released to the next neuron, and the amount of neurotransmitters released by the next neuron is different for different levels of stimulation, so mimic this process to build a neural network: When entering a data x, simulate input an outside stimulus, after process
I've been watching "neural network Design_hagan" Then you want to implement an XOR network yourself. Because the single layer neural network can not divide the different or the judgment to two kinds. According to a^b= (a~b) | (~AB) And I tried it. Or and with both ca

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
LSTM unit.for the gradient explosion problem, it is usually a relatively simple strategy, such as Gradient clipping: in one iteration, the sum of the squares of each weighted gradient is greater than a certain threshold, and to avoid the weight matrix being updated too quickly, a scaling factor (the threshold divided by the sum of squares) is obtained, multiplying all the gradients by this factor.

Http://www.cnblogs.com/python27/p/MachineLearningWeek05.html This chapter may be the most unclear chapter of Andrew Ng, why do you say so? This chapter focuses on the back propagation (backpropagration, BP) algorithm, Ng spent half time talking about how to calculate the error item δ, how to calculate the δ matrix, and how to use MATLAB to achieve the post transmission, but the most critical question-why so calculate. The previous calculation of these amounts represents what, Ng basically did n
If you use 100k batch in this model, and combine the decay of learning rate (that is, the rate of learning is reduced by a ratio every once in a while), the correct rate can be as high as 86%. There are about 1 million parameters to be trained in the model, and the total amount of arithmetic to be estimated is about 20 million times. So this convolution neural network model, using some techniques.(1) Regula
