/1406.2661.gan first Paper:lan Goodfellow generative adversarial Networks 5. Algorithm: Using random gradient descent method to train d,g. Specifically also in the above article. 6.DCGAN Principle Introduction: The best model for image processing applications in deep learning is CNN, how CNN and Gan combine. The answer is Dcgan. The principle is the same as Gan. Just replaced the above G and D with two convolutional

Before explaining the error back propagation algorithm, let's review the flow of the signal in the neural network. Please understand that when input vector \ (x\) input Perceptron, the first initialization weight vector \ (w\) is randomly composed, can also be understood as we arbitrarily set the initial value, and the input do dot product operation, and then the model through the weight update formula to c

the face have moved to another corner of the image, as shown in Fig. 3:The same number of activations occurs in this example, however they occur in a different region of the green and yellow VO Lumes. Therefore, any activation in the first slice of the yellow volume means that a-face is detected, independently of T He face location. Then the fully-connected layer was responsible to ' translate ' a face and a human body. In both examples, an activation is received at one of the fully-connected n

applicationsThe blogger made an open source project and collected paper and papers related to the network.Welcome to star and contribution.Https://github.com/zhangqianhui/AdversarialNetsPapersApplication to combat NN. These apps can all be found in my open source project .(1) The paper [2] uses CNN for image generation, where D is used for classification and has a good effect.(2) the thesis [3] uses the prediction of the video frame against NN, which solves the problem that other algorithms can

Hopfield Neural network usage instructions.There are two characteristics of this neural network:1, output value is only 0, 12,hopfield not entered (input)Here's a second feature, what do you mean no input? Because in the use of Hopfield network, more used for image simulatio

The article does not write clearly please forgive QaqIn this article we will make a very simple image classifier with the CIFAR-10 data set. The CIFAR-10 dataset contains 60,000 images. In this dataset, there are 10 different categories, with 6,000 images in each category. The size of each image is x 32 pixels. While such a small size often poses difficulties in identifying the right category for humans, it is actually a simplification of the computer model and reduces the computational complexi

The development of Googlenet inception V1:The well-designed Inception Module in the Inception V1 improves the utilization of the parameters, Nception V1 removes the final fully connected layer of the model, using the global average pooling layer (which changes the image size to 1x1), in the previous network, The whole connection layer occupies most of the network parameters, it is easy to produce the phenom

Training ResultsThe final output of the above model is:As can be seen from the print log, the early convergence rate is very fast and the late start fluctuates. Finally, the correctness rate of the model in training set is about 90%, and the test set is similar. Accuracy is still relatively low, it is explained that the single-layer

An example of image recognition based on convolutional neural network is the preprocessing of input image in common use. Step1:resize STEP2: Go to mean value. It should be noted here that the average is calculated for all training sample images, and then the average is subtracted from each sample picture. The test picture is also subtracted from the mean when i
