We thought that several channels were dominant in generating the final heat map. Faster-Score-CAM adds the processing of “use only channels with large variances as mask images” to Score-CAM. (max_N = -1
is the original Score-CAM).
When using VGG16, Faster-Score-CAM is about 10 times faster than Score-CAM.
