Explainable AI for Graph Neural Networks: Example Use of CAM and Grad-CAM

Class activation maps are almost always explained on images. This post applies CAM and Grad-CAM to a spatio-temporal graph network for human skeleton data, with the math, PyTorch code, and the architecture detail that decides whether the two methods give the same answer.
