Objective

Convolutional neural networks (CNN), the representative technology of deep learning, have the advantage of high performance, but the disadvantage of a black box for the reason for the output. For this reason, the application of CNNs has often been discouraged in fields where transparency of explanation is important, such as the medical field. Against this background, Class Activation Map (CAM) and Regression Activation Map (RAM) were proposed as methods to visualize the reasons for CNN output. However, CAM and RAM have the disadvantage that they are only applicable to simple CNN architectures. Therefore, Grad-CAM and Grad-RAM were newly proposed as applicable methods for complex CNN architectures. These methods have allowed deep learning to be used in areas where transparency is important. Therefore, machine learning engineers had better acquire this skill. In this lecture, the theory and implementation of CAM, RAM, Grad-CAM, and Grad-RAM will be explained as methods to white box CNNs.
In this course, students will acquire the theory and implementation of CAM, RAM, Grad-CAM, and Grad-RAM as methods to white box CNNs.
