useful when combined with a number of different random subsets of other neurons. The first two fully connected layers use dropout. Without dropout, our network would show a lot of overfitting. The dropout increases the number of iterations required for convergence by roughly one-fold.4. Image preprocessing① size NormalizationTo 256x256 all the pictures to the size of the scale, as for why not directly normalized to 224 (227), please refer to the above-mentioned expansion of the dataset operatio

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

value sharing (or weight reproduction) and time or spatial sub-sampling to obtain some degree of displacement, scale and deformation invariance.Question three:If the C1 layer is reduced to 4 feature plots, the same S2 is also reduced to 4 feature plots, with C3 and S4 corresponding to 11 feature graphs, then C3 and S2 connection conditionsQuestion Fourth:Full connection:C5 to the C4 layer convolution operation, the use of the full connection, that is, each C5 convolution core in S4 all 16 featu

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

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

visual comprehension of convolutional neural networks The first to suggest a visual understanding of convolutional neural Networks is Matthew D. Zeiler in the visualizing and understanding co
