In December 2015, Rethinking the Inception Architecture ofr Computer Vision, Inception V3, top-5, with an error rate of 3.5%. February 2016 Inception-v4, Inception-ResNet and the Impact of Residual Connections on Learning Inception V4, top-5 Error Rate 3.08%. Inception V2 uses two 3x3 convolution instead of the 5x5 convolution to reduce the number of parameters and overf
In some tasks, we need to train a number of different neural network models for different situations, at which point we need to call multiple pre-trained models to make predictions in the test phase. To call a single pre-trained model click here Figuring out how to invoke a single model is actually a logical way to invoke multiple models. We just need to build multiple graphs, then import a model for each diagram, and then create a session for each diagram to make predictions
, then Relu activated and then raised back to the original dimension through a fully connected layer. This is better than using a fully connected layer directly (1). With more nonlinearity, it can better fit the complex correlation between channels, 2). Greatly reduced the number of parameters and the amount of calculation. Then through the sigmoid door to get the 0~1 between the weights, and finally through a scale operation to the normalized weight weighted to each channel characteristics.In a
TensorFlow Get variables print weights and Other methods In the use of tensorflow, we often need to get the value of a variable, such as: print the weight of a layer, usually we can directly use the variable's Name property to get, but when we use some third party library to construct neural network layer, There is a situation where we cannot define variables of this layer ourselves because they are automatically defined. For example, when using TensorFlow's slim library: def resnet_stack (i
We fell for recurrent neural networks (RNN), Long-short term-memory (LSTM), and all their variants. Now it's time to drop them! IT is the year 2014 and Lstm and RNN make a great come-back from the dead. We all read Colah's blog and Karpathy ' s ode to RNN. But We were all young and unexperienced. For a few years this is the way to solve sequence learning, sequence translation (SEQ2SEQ), which also resulted in Amazin G results in speech to text comprehension and the raise of Siri, Cortana, Google

, only white box attacks will not cause a greater impact, it is scary to resist the migration of samples, which is the CAAD CTF such a directional generic attack feasible reasons. A portable attack means that we don't know what machine learning models, specific parameters, and training sets are used by the target, but we can train our own models and build confrontation samples from similar datasets, which are likely to deceive unknown target models because of the mobility.Then in 2016, researche

present a small convolutional network module DUC for the purpose of magnifying the feature map dimensions. The input to the DUC is the output of the ResNet network feature map HXWXC, we use DUC output feature map sizeHXWX (R*RXL), finally reshaped the input image size HXWXL. Completed the magnification workWhere L is the total number of categories of semantic segmentation, R is the downsampling factor in ResNet
and richer spatial features and increase the feature diversity. 3*3 convolution cores are split into 1*3 convolution and 3*1 convolution: On the other hand, Inception V3 optimizes the structure of the Inception module, and now Inception module has three different structures such as 35*35, 17*17, and 8*8. These inception module only appear at the back of the network, and the front is a normal convolution layer. Branches are also used in the branches of the inception module. I
extreme cases the residual f (x) is compressed to 0. ：The above is the residual unit of ResNet. The benefit of the residual unit is that when the response is propagated, the gradient can be passed directly to the upper layer, and the inefficient gradient disappears to support the deeper network. At the same time, ResNet also uses batch normalization, and the residual unit will be easier to train and more g

Some implementation details 1, combined with TensorFlow Slim In the original implementation, the author used the VGG19 model as a loss network. In the original paper, the VGG16 is used. To maintain consistency, I used the TensorFlow slim to repackage the loss network. Slim is an extended library of
Deep Residual network in the 2015 ILSVRC competition to achieve the first achievement, ICLR2016 is also one of the key issues. Its main idea is simply to add a hop to bypass some layers of connectivity on a standard feedforward convolution network. Each bypass layer produces a residual block (residual blocks), and the convolution layer predicts the residuals of the input tensor. As shown in the following illustration: Common depth feedforward networks are difficult to optimize. In addition to
