We know that convolutional neural Network (CNN) has been widely used in the field of image, in general, a CNN network mainly includes convolutional layer, pool layer (pooling), fully connected layer,
similar to the dimensionality reduction) method. Maximum pooling divides the input image into overlapping image matrix blocks, and each sub-region outputs its maximum value. The two reasons why the maximum pooling method is very effective in the visual processing problem are:(1) Reduce the computational complexity of the upper level by reducing the non-maximum value.(2) The result of pooling supports translation invariance. In the convolution layer, each pixel point has 8 orientations that can
content feature extraxtor or style feature extractor effect is not the same.
We find that matching the "style representations up" higher layers in the network preserves local images creasingly large scale, leading to a smoother and more continuous visual experience.
Accordingly, Conv (1-5) _1 was chosen as style layer
The following figure shows the different effects of different conv layer as content layer:

Unlike the simple Max-pooling method after the first layer, the pooling of the subsequent convolution layer is a dynamic pooling method , which derives from the reference [1].

The code also includes generating the commit file, running Python kfkd.py to find out how the command is exercised with this script.There's a whole bunch of obvious improvements you can make: try to optimize each ad hoc network
edge to 256 D to get B, and then in the center of B take 256*256 square picture to get C, and then randomly extract 224*224 on C as a training sample, and then in the combination of image level inverse increase the sample to achieve data gain. This gain method is 2048 times times the sample increase, allowing us to run a larger network.(2) Adjust the RGB valueThe specific idea is: To do PCA analysis of three channel, get the main component, make some

Why use convolution?
In traditional neural networks, such as Multilayer perceptron (MLP), whose input is usually a feature vector, requires manual design features, and then the values of these features to form a feature vector, in the past decades of experience, the characteristics of artificial found is not how to use, sometimes more, sometimes less, Sometimes the selected features do not work at all (the truly functional feature is inside the vast u
