Before revision:  We find that CheXseg improves upon the performance (mIoU) of fully-supervised methods that use only pixel-level expert annotations by 13.4 \% and weakly-supervised methods that use only DNN-generated saliency maps by 91.2\%.
After revision:  We find that CheXseg improves upon the performance (mIoU) of fully-supervised methods that use only pixel-level expert annotations by 9.7 \% and weakly-supervised methods that use only DNN-generated saliency maps by 91.2\%.
