ViM: Out-Of-Distribution with Virtual-logit Matching

Web11 de mai. de 2024 · Out-of-distribution (OOD) usually refers to the samples from an irrelevant distribution whose label set has no intersection with \mathcal {Y} and therefore should not be predicted by the model. We use \mathcal {D}_ {in} to train a neural network classification model f ( x ). WebOut-of-distribution (OOD) detection has recently gained substantial attention due to the importance of identifying out-of-domain samples in reliability and safety. Although OOD detection methods have advanced by a great deal, they are still susceptible to adversarial examples, which is a violation of their purpose. crosswise on a ship https://benalt.net

Web6 de abr. de 2024 · Such new test samples which are significantly different from training samples are termed out-of-distribution (OOD) samples. An OOD sample could be anything, which means it could belong to an arbitrary domain or category. These OOD samples can often lead to unpredictable DNN behavior and overconfident predictions [1]. WebMotivated by this observation, we propose a novel OOD scoring method named Virtual-logit Matching (ViM), which combines the class-agnostic score from feature space and the In-Distribution (ID) class-dependent logits. Specifically, an additional logit representing the virtual OOD class is generated from the residual of the feature against the ...
