I've implemented Grad Cam. The colors in a Grad-CAM heatmap usually use a red-to-blue color scale, where red signifies the highest importance and blue signifies the lowest importance. The intensity of the color represents the degree of importance. For example, a brighter red color indicates a higher importance for that region, while a darker blue color indicates a lower importance. but the output I got does not make any sense to me.
I used this method to implement grad cam.
