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 achieved very surprising results, The result is much

. Pretreatment: Mean removal;whitening (ZCA) Enhanced generalization capability: Data augmentation;weight regularization; adding noise to the network, including dropout,dropconnect,stochastic pooling. Dropout: The output of some neurons in the fully connected layer is randomly set to 0 at the full connection layer only. Dropconnect: Also only used on the full-connection layer, Random binary mask on weights. Stochastic Pooli

Network structureA.CNN based Feature ExtractionThe paper uses the Kitti data set.The CNN section has 9 convolutional layers, with the exception of CONV6, the other convolutional layers are connected to 1 layers of relu, and there are 17 layers.B, RNN based sequential modellingRNN is different from CNN

Purpose of the documentThe author hopes to improve the accuracy of CNN by modifying the model depth and the parameters of the convolution template, while maintaining the computational complexity. Through a lot of experiments, the author finds the importance of different parameters in the

. 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

scientists have contributed significantly to the success of convolutional networks?There is no doubt that the neuro-cognitive machine (Neocognitron) proposed by Japanese scholar Kunihiko Fukushima has enlightening significance. Although the early forms of convolutional networks (Convnets) did not contain too many Neocognitron, the versions we used (with pooling layers) were affected.This is a demonstration

(1980) in the neuro-cognitive machine article, the self-organizing neural network model of pattern recognition mechanism is not affected by the change of position.Can you recall the "epiphany" moments or breakthroughs that occurred in the early days of

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.

Because there may be many objects in the graph, the multi-class classification loss is not applicable. The author sees this task as multiple two classification questions, loss function and classification score as followsTrainingMuti-scale TestExperimentClassification MAP on VOC test: +3.1% compared with [56] MAP on VOC test: +7.
