Deep Learning paper notes (IV.) The derivation and implementation of CNN convolution neural network[Email protected]Http://blog.csdn.net/zouxy09 I usually read some papers, but the old feeling after reading will slowly fade, a day to pick up when it seems to have not seen the same. So want to get used to some of the feeling useful papers in the knowledge points summarized, on the one hand in the process of finishing, their own understanding will be de
Girshick, Ross. "Fast r-cnn." Proceedings of the IEEE International Conference on computer Vision. 2015.Following the 2014 RCNN, Ross Girshick introduced fast rcnn in 15, with a sophisticated and compact process that significantly increased the speed of target detection. The source code is available on GitHub.The reason why fast r-cnn is proposed is mainly because R-CNN
this is: in convolutional neural network CNN, the area of the input layer corresponding to an element in a certain layer of output is called the receptive field.????

the tutorial you don't really need to run the code here, but if you have a CUDA-enabled GPU on hand and want to follow the steps of the tutorial to execute the code, here are a few guidelines:1, let's say your support for Cuda's GPU is already ready, and Python2.7.x,numpy,pandas,matplotlib,scikit-learn is already installed.2, install a virtualenv, and activate the virtual environment.3. Install lasagne directly from GitHub, run the following command
use the same algorithm as BP networks. Therefore, using the existing BP network can be achieved. Open source Neural Network code Faan can be exploited. This open source implementation uses a number of code optimization techniques, with double precision, single-precision, fixed-point operation three different versions. Because the classical BP network is a one-dimensional node distribution arrangement, convolutional Neural Network is a two-dimensional network structure. So, in order to map ea
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.
CNN convolutional Neural network key points:{1} is a non-fully connected network (sparse network), compared to the BP neural network (fully connected network), of course, CNN can also have a portion of the layer is the full connection layer.{2} weight sharing (the same weight factor), which is the same as the convolution kernel (location independent), 1 convolution cores. 1 convolution cores correspond to a
1 PrefaceIn my previous blog, I introduced some of the ways to run CNN on iOS. But, in general, we need a powerful machine to run the CNN, we just need to use the resulting results for the mobile side. Before the code modified using UFLDL in MATLAB ran the 3-layer CNN of hand recognition, here we consider porting Matlab to Xcode.Step 1:matlab Turn CThe first thin
Cnn-convolutional Neural NetworksIn recent years in the field of machine vision is a very fire of acquiescence, first proposed by Yan LeCun.If you want to learn the details, see Li Feifei cs231n courseHow does it work?Give a picture, each circle is responsible for processing part of the picture.These circles form a filter.Filter identifies whether the specified pattern exists in the picture and in which region.There are 4 filter in the same color, the
This paper combines the application of deep learning, convolution neural Network for some basic applications, referring to LeCun's document 0.1 for partial expansion, and results display (in Python).Divided into the following parts:1. Convolution (convolution)2. Pooling (down sampling process)3. CNN Structure4. Run the experimentThe following are described separately.PS: This blog for the ESE machine learning short-term class reference (20140516 cours
