A high domain shift tends to implicate in a poor generalization performance from the models. In this work, we evaluate the extent of domain shift on four of the largest datasets of chest radiographs. ...
We show how training and testing with different datasets (e.g., training in ChestX-ray14 and testing in CheXpert) drastically affects model performance, posing a big question over the reliability of deep ...
Our experiments show that a model with reported radiologist-level performance had a huge drop in performance outside its source dataset, pointing the existence of domain shift in chest X-rays datasets. ...
