Class Activation Mapping: the predicted class score is mapped back to the previous convolutional layer to generate the class activation maps (CAMs). The CAM highlights the class-specific discriminative regions. Here we ignore the bias term: we explicitly set the input bias of the softmax to 0 as it has little to no impact on the classification performance. By plugging Fk = x,y fk(x, y) into the class score, Sc, we obtain Sc = k wc k x,y fk(x, y) = x,y k wc kfk(x, y). (1) We define Mc as the class activation map for class c, where each spatial element is given by Mc(x, y) = k wc kfk(x, y). (2) Thus, Sc = x,y Mc(x, y), and hence Mc(x, y) directly indicates the importance of the activation at spatial grid (x, y) leading to the classification of an image to class c. Intuitively, based on prior works [34, 30], we expect each unit to be activated by some visual pattern within its recep- Figure 3. The CAMs of two classes from ILSVRC [21]. The maps highlight the discriminative image regions used for image classification, the head of the animal for briard and the plates in barbell.
