the composition of a convolutional neural network Image classification can be considered to be given a test picture as input Iϵrwxhxc Iϵrwxhxc, the output of this picture belongs to which category. The parameter W is the width of the image, H is the height, C is the number of channels, and C = 3 in the color image, and C = 1 in the grayscale image. The total number of categories will be set, for example in

R using convolutional neural networks to make predictions

Deep learning over the past few years, the feature extraction capability of convolutional neural Networks has made this algorithm fire again, in fact, many years ago, but because of the computational complexity of deep learning problems, has not been widely used. As a general rule, the convolution layer is calculated in the following form: where x represents the

How to understand weight sharing in convolutional neural networks

Weight sharing the word was first introduced by the LENET5 model, in 1998, LeCun released the Lenet network architecture, which is the following:Although most of the talk now is that the 2012 Alexnet network is the beginning of deep learning, the beginning of CNN can be traced back to the LENET5 model, and its features are widely used in the study of convolutional neural

holds.Each neuron also holds its own output value (double). The Nnconnection and Nnweight classes store some information separately.You may wonder why the weights and connections are defined separately? According to the above principle, each connection has a weight, why not directly put them in a class?The reason: weights are often shared by the connection.In fact, the weighted value of the shared connection is in the convolutional

in the second layer.The formula is:The original image is mapped to, 0-255, here is generally set to 8, function h is a step function. , which indicates the number of filters in the second layer.For each output matrix of the first layer, it is divided into B block, calculate the histogram information of each block, then cascade the histogram features of each block, and finally get the Block expansion histogram feature:Overlapping and non-overlapping block patterns can also be used for histogram
