Learning Transferable Negative Prompts for Out-of-Distribution Detection

1 code implementation4 Apr 2024 Tianqi Li, Guansong Pang, Xiao Bai, Wenjun Miao, Jin Zheng

Existing prompt learning methods have shown certain capabilities in Out-of-Distribution (OOD) detection, but the lack of OOD images in the target dataset in their training can lead to mismatches between OOD images and In-Distribution (ID) categories, resulting in a high false positive rate.

Out-of-Distribution Detection in Long-Tailed Recognition with Calibrated Outlier Class Learning

1 code implementation17 Dec 2023 Wenjun Miao, Guansong Pang, Tianqi Li, Xiao Bai, Jin Zheng

To this end, we introduce a novel calibrated outlier class learning (COCL) approach, in which 1) a debiased large margin learning method is introduced in the outlier class learning to distinguish OOD samples from both head and tail classes in the representation space and 2) an outlier-class-aware logit calibration method is defined to enhance the long-tailed classification confidence.
