This paper proposes AbeT, a novel Out-of-Distribution (OOD) detection method that significantly improves performance over existing approaches without requiring multiple stages or hyperparameters. By lowering the False Positive Rate at 95% True Positive Rate (FPR@95) by 43.43%, AbeT demonstrates its effectiveness in identifying OOD samples in classification tasks. The paper also provides insights into why AbeT learns to distinguish between In-Distribution (ID) and OOD samples, despite only being explicitly trained on ID examples. Furthermore, the authors demonstrate the efficacy of AbeT in object detection and semantic segmentation tasks, achieving an AUROC increase of 5.15% in object detection and a decrease in FPR@95 of 41.48% and an increase in AUPRC of 34.20% in semantic segmentation compared to previous state-of-the-art methods.

AbeT is a new way to help computers figure out when they’re looking at something that’s not normal or expected. This is important because sometimes computers can be very sure about things, but what if it’s actually wrong? AbeT helps by learning what normal things look like and then spotting when something looks different. It’s better than other methods at finding these differences and can even help with tasks like identifying objects in pictures or detecting unusual pixels.
