(English Abstract)
Among the various deep learning techniques available, convolutional neural networks (CNNs) are widely used due to their superior performance in the fields of computer vision and natural language processing. CNNs can effectively extract the locality and correlation of input data using structures wherein convolutional layers are successively applied to the input data. The performance of neural networks has generally been improved as the depth of CNNs has increased. However, an increase in the depth of a CNN is not always accompanied by a corresponding increase in the accuracy of the neural network. This is because the gradient vanishing problem may occur, thereby causing the weights of the weighted layers to fail to converge. Accordingly, in the present study, the gradient flows of the VGGNet model, ResNet model, and DenseNet model were analyzed and compared, and reasons for the differences in the error rate performances of the models was derived.
