I have trained a model to figure out if an image is right or wrong (just 2 classes) and I have used the guide on keras website for GradCAM . The input images are reshaped to (250, 250) and then normalized by dividing the image numpy array by 255. This is then passed for the training of the model. Here is the code attached.

Webb29 maj 2024 · Grad-CAM is a generalization of CAM (class activation mapping), a method that does require using a particular architecture. CAM requires an architecture that applies global average pooling (GAP) to the final convolutional feature maps, followed by a single fully connected layer that produces the predictions: http://www.xiamenjiyang.com/products_show.asp?id=2248
