Deep Learning Database Summary Thanks for the collection. Source: https://blog.csdn.net/chaipp0607/article/details/71403797 The preparation of the data is necessary to train the model, which is obviously time-consuming, so we can use the existing open source image Library to quickly prepare for the initial work in the introductory phase: ImageNet Imagenet is an

A summaryIn this paper, we present a very simple image classification deep learning framework, which relies on several basic data processing methods: 1) Cascade principal component Analysis (PCA), 2) Two value hash coding, 3) chunking histogram. In the proposed framework, the multi-layer filter kernel is first studied by PCA method, and then sampled and encoded u

vector to the discriminator to discriminate the probability that the generator is generated by the hidden space vector. Use real, fake pictures with real/fake tags to train discriminator; To train generator, you can use the GAN model to lose the gradient of the generator weight. This means that in each step, the weight of the generator is moved to the direction that the discriminator is more likely to classify the image decoded by the generat

in the previous section.We want the additional layer to learn the identity mapping, which is still very difficult to train because it is a non-linear layer .However, if we are learning the residual mapping, that is, the total zero residuals, it is obviously much easier . Thought is similar to SVM, but you can't think of it!!! Iv. Implementation Shortcut connectionsThought has, concrete how to achieve it?Can't help: He Dashen too awesom

For supervised learning algorithms, the data determines the upper limit of the task, and the algorithm just keeps approaching the upper limit. The furthest distance in the world is that we use the same model, but we have different tasks. But data labeling is a time-consuming effort, and here are a few image labeling tools: LabelMe LabelMe data set for image

Experimental results:

, the gradient method of the output unit also changes: Because the output layer f (z) = z, f '(Z) = 1, so: When the back propagation is used to calculate the error, it is still the same as before: This is because the incentive function of the hidden layer or the sigmoid function has not changed. The following exercises use a linear encoder to learn the features of color images, dataset features: After whitening: Learned features: It can be seen that, like a g
