abstract = {In this paper, for the first time, we propose an evaluation
method for deep learning models that assesses the
performance of a model not only in an unseen test scenario,
but also in extreme cases of noise, outliers and ambiguous
input data. To this end, we utilize adversarial examples,
images that fool machine learning models, while looking
imperceptibly different from original data, as a measure to
evaluate the robustness of a variety of medical imaging
models. Through extensive experiments on skin lesion
classification and whole brain segmentation with
state-of-the-art networks such as Inception and UNet, we
show that models that achieve comparable performance
regarding generalizability may have significant variations
in their perception of the underlying data manifold, leading
to an extensive performance gap in their robustness.},
