latest progress in deep learning--the anti-neural network. It mainly includes the idea of resisting the neural network and two specific Gan networks, the deep convolution countermeasure Generation Network (Dcgan) and the image translation (PIX2PIX) model. The knowledge points involved include generator G, discriminant D, deconvolution, u-net and so on. ... 10th Automatic Machine Learning Network-AUTOML This course provides an explanation of the latest advances in deep learning-automated machine

1. Import various modulesThe basic form is:Import Module NameImport a module from a file2. Import data (take two types of classification issues as an example, Numclass = 2)Training Set DataAs you can see, data is a four-dimensional ndarrayTags for training sets3. Convert the imported data to the data format I keras acceptableThe label format required for Keras should be binary class matrices, so you need to convert the input label data to take advantage of the Keras enhanced to_categorical funct

A number of well-known websites such as CNN have encountered error 503 errors recently, according to foreign media reports. Foreign media said, according to users, affected by the social news site, including Reddit, The New York Times, CNN, BuzzFeed and other well-known sites, their network management system has a big problem.▲CNN and many other well-known sites

The biggest problem with full-attached neural networks (Fully connected neural network) is that there are too many parameters for the full-connection layer. In addition to slowing down the calculation, it is easy to cause overfitting problems. Therefore, a more reasonable neural network structure is needed to effectively reduce the number of parameters in the neural network. convolutional Neural Networks (convolutional neural network,cnn) can do that.

: Train multiple models, averaging the results when you test, and you can get a 2% boost. When training a single model, the results of checkpoints in the average different periods can also be improved. You can combine the parameters of the test with the parameters of the training when testing: 1. Whether CNN or Rnn,batch normalization useful, not necessarily result in a few points, convergence is much

is Faster r-cnn Doing well for pedestrian Detection?ECCV Liliang Zhang kaiming He　　Original link: http://arxiv.org/pdf/1607.07032v2.pdf　　Abstract: Pedestrian detection is argue said to be a specific subject, rather than general object detection. Although recent depth object detection methods such as: Fast/faster RCNN in general object detection, show a strong performance, but for pedestrian detection is not very successful.

The receptive field is a kind of thing, from the angle of CNN visualization, is the output featuremap a node response to the input image of the area is to feel wild.For example, if our first layer is a 3*3 core, then each node in the Featuremap that we get through this convolution is derived from this 3*3 convolution core and the 3*3 region of the original image, then we call this Featuremap node to feel the wild size 3*3If you go through the pooling

So, for the Cbow model, there are:Then, the target function is:Then the parameters θ and x of the target function are updated by the random gradient descent method, so that the value of the objective function can be maximized.Similar to the Cbow model, Skip-gram is solved by optimizing the following objective functions.whichSo, the target function of Skip-gram is:The parameters θ and V (w) of the t

,In the above formula, the * number is the convolution operation, the kernel function k is rotated 180 degrees and then the error term is related to the operation, and then summed.Finally, we study how to calculate the partial derivative of the kernel function connected with the convolution layer after obtaining the error terms of each layer, and the formula is as follows.The partial derivative of the kernel function can be obtained when the error item of the convolution layer is rotated 180 deg
