Record completeness
Claims
We show that such maps can be employed for weakly supervised object segmentation using classification ConvNets.
That the gradient of the class score with respect to the input image pixels provides a faithful measure of pixel importance or saliency for the model's decision.
Gradient ascent on class scores and input-image gradients produce visualizations of ConvNet class notions and saliency maps usable for weakly supervised segmentation.
