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, convolution neural network is a two-dimensional network structure. So, in order to map each layer of convolutional neural network into one-dimensional node distribution according to a certain se

The first day of CNN Basics From:convolutional Neural Networks (LeNet) neuro-Cognitive machines .The source of CNN's inspiration has been very comprehensive in many papers, and it is the great creature that found receptive Field (the sensation of wild cells). Based on this concept, a neuro-cognitive machine is proposed. Its main function is to recept part of the image information (or characteristics), and then through the hierarchical submission o

convolutional Neural Networks (convolution neural network, CNN) have achieved great success in the field of digital image processing, which has sparked a frenzy of deep learning in the field of natural language processing (Natural Language processing, NLP). Since 2015, papers on deep learning in the field of NLP have emerged. Although there must be a lot of arty hydrology, there are many classic application-oriented articles. In 2016, I also published

Introduction to convolutional Neural Networks Convolutional neural network is a multi-layer neural network that specializes in processing machine learning problems related to images, especially big images. The most typical convolutional network consists of a convolution layer, a pooling layer, and a full connection layer. The convolution layer works with the pooling layer to form multiple convolution groups, extract features layer by layer, and finally complete classification through several ful
