Neuron Model　　Neurons can be thought of as a computational unit that receives certain information from the input nerves, makes some calculations, and then transmits the results to other nodes or other neurons in the brain through axons.The neuron is modeled as a logical unit, as follows:　　In, the input unit is X1 X2 X3, sometimes can also be added x0 as offset units, the value of x0 is 1, whether to add bias units depends on whether it is advantageous to the example.The Orange small Circle in th

relevant people to have a deeper understanding of the business.Another way of thinking about model work is "complex model + simple features". That is, to weaken the importance of feature engineering and to use complex nonlinear models to learn the relationship between features and to enhance their expressive ability. The deep neural network model is such a non-linear model.is a deep

seen before, and if it has a similar word (similar in meaning) to the sentence we have seen, it will have a higher probability, so that it will gain generalization. It is challenging to train such a large model (with millions of parameters) within a reasonable time. The report that we use neural networks to compute probability functions shows that the method presented in two text corpora significantly improves the most advanced n-ary syntax model, an

Here is the [1] derivation of the BP algorithm (backpropagation) steps to tidy up, memo Use. [1] the direct use of the matrix differential notation is deduced, the whole process is very concise. And there is a very big advantage of this matrix form is that it is very convenient to implement the programming Control.But its practical scalar calculation deduction also has certain advantages, for example, can clearly know that a weight is affected by who.Marking Conventions:$L $: The number of layer

1 Introduction An XOR operation is a commonly used calculation in a computer: 0 XOR 0 = 0 0 XOR 1 = 1 1 XOR 0 = 1 1 XOR 1 = 0 We can use the code in the first article to calculate this result Http://files.cnblogs.com/gpcuster/ANN1.rar (need to modify the training set), we can find that the results of learning does not satisfy us, because the single layer of neural network learning ability is limited ,

I've been focusing on CNN implementations for a while, looking at Caffe's code and Convnet2 's code. At present, the content of the single-machine multi-card is more interested, so pay special attention to Convnet2 about MULTI-GPU support.where Cuda-convnet2 's project address is published in: Google Code:cuda-convnet2A more important paper on MULTI-GPU is: one weird trick for parallelizing convolutional neural NetworksThis article will also give an a

However, there are few learning materials related to Rnns online, so this series is to introduce the principle of rnns and how to achieve i

In the deep network, the learning speed of different layers varies greatly. For example: In the back layer of the network learning situation is very good, the front layer often in the training of the stagnation, basically do not study. In the opposite case, the front layer learns well and the back layer stops learning.This is because the gradient descent-based learning algorithm inherently has inherent inst
