[R] Resources Critiquing Grad-CAM Paper Versions

Hello everyone,

I'm writing a report about the Grad-CAM paper that was published a few years ago. During my research, I discovered that there are multiple versions of this paper, ranging from version 1 to version 4. I am particularly interested in finding resources that critique the shortcomings of the earlier versions and what changed in the other versions.

If anyone could point me toward any such resources, it would be greatly appreciated.

Thank you!
