Grad-CAM studio
Inspect exactly which pixels drove the prediction — pixel by pixel, region by region.
Controls
Reading the map
Warm regions (mango → sunset) contributed most to the prediction. Cool regions (indigo → turquoise) were largely ignored by the model.
Strong evidence · right lower lobe
Supporting · costophrenic angle
Negligible · upper fields
Method
Gradient-weighted CAM
Activations from the final convolutional block are weighted by their gradient w.r.t. the predicted class, then upsampled to the image grid. No region is hidden from review.
