convolutional neural network example

AlexNet: (ILSVRC Top 5 test error rate of 15.4%) the first successful display of the convolutional neural network potential network structure. key point: with a large amount of data and long-time training to get the final model, the results are very significant (get 2012 classification first) using two GPU, divide

Original articleReprint please register source HTTP://BLOG.CSDN.NET/TOSTQ the previous section we introduce the forward propagation process of convolutional neural networks, this section focuses on the reverse propagation process, which reflects the learning and training process of neural networks. Error back propagation method is the basis of

How to understand the status of NLP: see some tips for the latest doctoral dissertationIt may be a shortcut to look at the current status of an area and see the latest doctoral dissertation. For example, there are children's shoes asked how to understand the State-of-the-art of NLP, in fact, Stanford, Berkeley, CMU, JHU and other schools recently

Study, the use of convolutional neural network has been a long time, the period has been based on the Caffe framework of the Jiayanqing great God to study other people's model, or in the boring time in the same way as the fortune-telling, eyes micro-closed, bobbing, the mouth occasionally leaking a few syllables, a long time DIY out of a think of a lot of models,

subsequent identification process. Some scholars also combine evolutionary computing theory with a neuro-cognitive machine, which makes the network pay attention to the different characteristics to help improve the distinguishing ability by weakening the training and learning of repetitive excitation features. All of these are the development process of neuro-cognitive machine, and convolutional

Transferred from: http://blog.csdn.net/u014380165/article/details/77284921 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,

biased term, followed by a nonlinear function. If you use $h ^{k}$ to represent the feature map of the $k $ layer, the corresponding filter is determined by the $W ^{k}$ and bias $b _{k}$, then the feature map $h ^{k}$ can be computed from the next (using Tanh for nonlinear functions):$h _{ij}^{k}=tanh (w^{k}*x) _{ij}+b_{k}$In order to get a richer representation of the data, each hidden layer is usually composed of multiple feature graphs: $\{h^{\text{(k)}},k=0,... k\}$. The weight $W $ is rep
