this you can make your Exi Sting DataSet even larger, just with a couple easy transformations. Like the we ' ve mentioned before, when a computer takes an image as an input, it'll take in an array of pixel values. Let's say that the whole image is shifted left by 1 pixel. To your and me, this is imperceptible. However, to a computer, this shift can is fairly significant as the classification or label of th

) Calculate the corresponding actual output op.At this stage, the information is transferred from the input layer to the output layer through a gradual transformation. This process is also the process that the network executes when it is running properly after the training is completed. In this process, the network performs a calculation (in effect, the input is multiplied by the weight matrix of each layer, resulting in the final output):OP=FN (...

Why use convolution? In traditional neural networks, such as Multilayer perceptron (MLP), whose input is usually a feature vector, requires manual design features, and then the values of these features to form a feature vector, in the past decades of experience, the characteristics of artificial found is not how to use, sometimes more, sometimes less, Sometimes the selected features do not work at all (the

I. Convolutionconvolutional Neural Networks (convolutional neural Networks) are neural networks that share parameters spatially. Multiply by using a number of layers of convolution, rat

is the number of nodes related to the classification, assuming that we are set to 10 classes, the output layer is 10 nodes, the corresponding expectations of the setting in the multilayer neural network has been introduced, each output node and the above hidden layer 100 nodes connected, total (100+1) *10=1010 link line, 1010 weights.As can be seen from the above, the core of convolutional

. This vector input is further classified into the traditional fully-connected neural network (fully connected networks).　　All feature graphs in the C1, S2, C3, S4 layers in the diagram can define the image size with pixel x pixels. Would you say that the size of the image is not defined by pixel x pixels? Yes, but it's a bit special here, because these feature graphs make up the

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 image and sample them. CNN combines features,
