Axiom-based GradCAM

Axiom-based GradCAM or X-GradCAM is an enhanced version of GradCAM that satisfies two explainability axioms—sensitivity and conservation.

Let's assume that FlRh×w\mathcal{F}_l \in \R^{h \times w} is the lthl^{th} feature map obtained from the penultimate convolutional layer (hh and ww are the height and width of the feature map) and Fl(i,j)\mathcal{F}_l(i,j) ...
