It is one of the first shallow Convolutional neural network designed specifically to classify handwritten digit. Binary classification is the task of classifying the elements of given set into two groups on the basis of classification rule. By classification, we mean ones where the data is classified by categories. As can be seen in Figure 5a, the accuracy increased with the expansion of epochs, and the model finally reached an accuracy of 0. Convolutional neural networks usually have far more than just three layers. The structure of the net-work is replicated across the top and bottom sections to form twin networks, with shared weight matrices at each layer. Only winner neurons are trained.
