2021 arXiv   pre-print
In this work, we assess the capability of various state-of-the-art approaches for confidence-based OOD detection through a comparative study and in-depth analysis.  ...  For critical applications such as clinical decision making, it is important that a model can detect such out-of-distribution (OOD) inputs and express its uncertainty.  ...  In this work, we first explore confidence-and distance-based approaches for out-of-distribution (OOD) detection on a standard computer vision (CV) task and afterwards evaluate the best OOD detection methods  ...
