Web25 de set. de 2024 · The highest AUROC over all methods is achieved by Mahalanobis distance both as a single model and an ensemble. Moreover, none of the OOD detection methods compromised the accuracy on the classification task. We reproduced the results of original implementation of DUQ with ResNet50. Web14 de abr. de 2024 · In general, the existing OOD detection methods can be roughly divided into two categories, i.e., supervised methods and unsupervised methods. Most of the supervised methods try to construct pseudo-OOD instances for (C+1)-way training, where C is the number of IND classes and the additional class represents the OOD intents, such …
