As a free from the vulgar Code of the farm, the Spring Festival holiday Idle, decided to do some interesting things to kill time, happened to see this paper: A neural style of convolutional neural networks, translated convolutional neura

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 ne

In this blog post we briefly analyze the class--layers of the last network structure in the TINY_CNN convolutional neural network model.First of all, layers can be called a layer structure of the vector, that is, the layer structure of the container. Because convolutional

UFLDL Learning notes and programming Jobs: convolutional neural Network (convolutional neural Networks)UFLDL out a new tutorial, feel better than before, from the basics, the system is clear, but also programming practice.In deep learning high-quality group inside listen to

with a (c,0,1) Form, where C represents the channel (color), and 0 and 1 correspond to the x and y dimensions of the image. In our question, the specific three-dimensional matrix is (1,96,96), because we only use grayscale as a color channel.A function load2d the above load function to complete the 2-dimensional to three-dimensional transformation: def load2d(test=False, cols=None): X, y = load(test=test) X = X.reshape(-119696) return X, yWe are going to create a

C ++ convolutional neural network example: tiny_cnn code explanation (10) -- layer_base and layer Class Structure Analysis
In the previous blog posts, we have analyzed most of the layer structure classes. In this blog post, we plan to address the last two layers, it is also the two basic classes layer_base and layer th

Transfer from http://blog.csdn.net/zouxy09/article/details/8781543CNNs is the first learning algorithm to truly successfully train a multi-layered network structure. It uses spatial relationships to reduce the number of parameters that need to be learned to improve the training performance of the general Feedforward BP algorithm. In CNN, a small part of the image (local sensing area) as the lowest layer of the input of the hierarchy, the information i

I've been focusing on CNN implementations for a while, looking at Caffe's code and Convnet2 's code. At present, the content of the single-machine multi-card is more interested, so pay special attention to Convnet2 about MULTI-GPU support.where Cuda-convnet2 's project address is published in: Google Code:cuda-convnet2A more important paper on MULTI-GPU is: one weird trick for parallelizing

C ++ convolutional neural network example: tiny_cnn code explanation (9) -- partial_connected_layer Structure Analysis (bottom)
In the previous blog, we focused on analyzing the structure of the member variables of the partial_connected_layer class. In this blog, we will continue to give a brief introduction to other m

,In the above formula, the * number is the convolution operation, the kernel function k is rotated 180 degrees and then the error term is related to the operation, and then summed.Finally, we study how to calculate the partial derivative of the kernel function connected with the convolution layer after obtaining the error terms of each layer, and the formula is as follows.The partial derivative of the kernel function can be obtained when the error item of the convolution layer is rotated 180 deg

I. Convolutionconvolutional Neural Networks (convolutional neural Networks) are neural networks that share parameters spatially. Multiply by using a number of layers of convolution, rather than a matrix of layers. In the process of image processing, each picture can be regarded as a "pancake", which includes the height

convolutional neural network for CNN. The C-layer represents all the layers that are obtained after filtering the input image, also called "convolution layer". The S layer represents the layer that the input image is sampled (subsampling) to get. Where C1 and C3 are convolution layers, S2 and S4 are the next sampling layers. Each layer in the C, S layer consists

convolutional neural Network (CNN) is the foundation of deep learning. The traditional fully-connected neural network (fully connected networks) takes numerical values as input.If you want to work with image-related information, you should also extract the features from the

Network Steps to do: (a Chinese, teach Chinese, why write a bunch of English?) ）1, sample Abatch of data (sampling)2,it through the graph, get loss (forward propagation, get loss value)3,backprop to calculate the geadiets (reverse propagation calculation gradient)4,update the paramenters using the gradient (using gradient update parameters)What convolutional neural

The neural network can be seen in two ways, one is the set of layers, the array of layers, and the other is the set of neurons, which is the graph composed of neuron.In a neuron-based implementation, you need to define two classes of Neuron, WeightAn instance of the neuron class is equivalent to a vertex,weight consisting of a linked list equivalent to an adjacency table and a inverse adjacency table.In the
