Disclaimer: Now, I did realize that some of these topics is quite complex and could be made in whole posts by themselves. In a effort to remain con

convolution layer of the error-sensitive items, because the reverse propagation when the output is smaller than the input, so the gradient at the time of transmission and traditional BP algorithm, So how to get the error-sensitive item of convolutional layer is the problem to consider. The third problem is to consider the pooling layer below the convolution layer, this is because we want to get the pooling layer error sensitivity, relying on the conv

ImageNet classification with deep convolutional neural Networks reading notes(after deciding to read a paper each time, the notes are recorded on the blog.) ）This article, published in NIPS2012, was Hinton and his students, in response to doubts about deep learning, used deep learning for imagenet, the largest database of image recognition, and eventually achieve

Some methods of himself analysis (II.) will be supplemented in the future. --by weponCombined with the literature "deep Learning for computer Vision", here are some points of attention and questions about convolutional neural networks. The excitation function is to choose a nonlinear function, such as tang,sigmoid,rectified liner. In CNN, Relu is used more be

. We use the cublas. lib and curand. Lib libraries. One is matrix calculation and the other is random number generation. I applied for all the memory I needed at one time. After the program started running, there was no data exchange between the CPU and GPU. This proved to be very effective. The program performance is about dozens of times faster than the original C language version (if the network is relatively large, it can reach a speed-up ratio of about one hundred times ). Each EPOS uses 16

In both CNN (1) and CNN (2) Two articles, the main explanation is CNN's basic architecture and weight sharing (Weight sharing), this article focuses on the convolution part.First, before convolution, our data is 4D tensor (width,height,channels,batch), which was mentioned in CNN (1): Architecture. The passage here, and the previously mentioned depth, is a concept, such as a grey scale image with a channel number of 1;RGB graphs of 3.In fact, Kernel also has channel, and its number is the same as

Wang, Min, Baoyuan Liu, and Hassan Foroosh. "Factorized convolutional neural Networks." ArXiv preprint (2016). This paper focuses on the optimization of the convolution layer in the deep network, which has three unique features:-Can be trained directly . You do not need to train the original model first, then use the sparse, compressed bits and so on to compress.

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 effective
