The mnist examples of convolutional neural networks and the neural network examples in the previous blog post are mostly the same. But CNN has more layers, and the network model needs to be built on its own.The procedure is more complicated, I will be divided into several pa

1.computer Vision CV is an important direction of deep learning, CV generally includes: image recognition, target detection, neural style conversion Traditional neural network problems exist: the image of the input dimension is larger, as shown, this causes the weight of the W dimension is larger, then he occupies a larger amount of memory, calculate W calculati

value of the C3 layer according to the local gradient δ value. (2) The weight of the C3 layer updates the value. C3 layer 6*12 A 5*5 template, we first define N=1~6,M=1~12 represents the label of the template, S,t represents the location of the parameters in the template (3) Weight update formula of C1 layer and field gradient δ value Similarly, we can also get the C1 layer weight update formula, here the m=6,n=1, and y refers to the input image the sampling layer S2 of the convolution

Study, the use of convolutional neural network has been a long time, the period has been based on the Caffe framework of the Jiayanqing great God to study other people's model, or in the boring time in the same way as the fortune-telling, eyes micro-closed, bobbing, the mouth occasionally leaking a few syllables, a long time DIY out of a think of a lot of models,

Turn from: The Heart of the machine Introduction Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult. Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations and manually perform these steps (and calcula

of pre-training network:Ultimately, this solution is 2.13 RMSE on the leaderboard.Part 11 conclusionsNow maybe you have a dozen ideas to try and you can find the source code of the tutorial final program and start your attempt. The code also includes generating the commit file, running Python kfkd.py to find out how the command is exercised with this script.Ther
