Diagnose like a Radiologist: Attention Guided Convolutional Neural Network for Thorax Disease Classification.
TL;DR: A three-branch attention guided convolution neural network (AG-CNN) that learns from disease-specific regions to avoid noise and improve alignment, and also integrates a global branch to compensate the lost discriminative cues by local branch.

Multi-label chest X-ray image classification via category-wise residual attention learning
TL;DR: A category-wise residual attention learning (CRAL) framework that predicts the presence of multiple pathologies in a class-specific attentive view and yields the average AUC score of 0.816 which is a new state of the art.

TL;DR: This paper proposes to integrate the global and local cues into a three-branch attention guided convolution neural network (AG-CNN) to identify thorax diseases and demonstrates that after integrating the local cues with the global information, the average AUC scores are improved by AG-CNN.

GraphNet: Learning Image Pseudo Annotations for Weakly-Supervised Semantic Segmentation
TL;DR: This paper proposes a novel graph convolutional network-based method, called GraphNet, to learn pixel-wise labels from weak annotations, which is effective to predict the pixel labels with scribble or bounding box annotations.
Proceedings ArticleDOI
EDTER: Edge Detection with Transformer
TL;DR: A novel transformer-based edge detector, Edge Detection TransformER (EDTER), to extract clear and crisp object boundaries and meaningful edges by exploiting the full image context information and detailed local cues simultaneously.
