WebAug 15, 2024 · Look at the Grad-CAM heatmaps in figure 12, our the biased model, we can observe that the model focuses on unwanted features ( part of the face, hair ) which seem insignificant while predicting labels ‘nurse’ and ‘doctor’. The model seems to learn gender-based features which aren’t appropriate in our use-case. WebAug 17, 2024 · Grad CAM is similar to CAM in that it is a weighted combination of feature maps but followed by a ReLU. The output of Grad CAM is a “class-discriminative localization map” where the hot part of the heatmap corresponds to a particular class.
