Out-of-Distribution Detection via Conditional Kernel Independence Model

NeurIPS 2022accept

Recently, various methods have been introduced to address the OOD detection problem with training outlier exposure. These methods usually count on discriminative softmax metric or energy method to screen OOD samples. In this paper, we probe an alternative hypothesis on OOD detection by constructing…

Improving Self-supervised Learning with Automated Unsupervised Outlier Arbitration

NeurIPS 2021poster

Our work reveals a structured shortcoming of the existing mainstream self-supervised learning methods. Whereas self-supervised learning frameworks usually take the prevailing perfect instance level invariance hypothesis for granted, we carefully investigate the pitfalls behind. Particularly, we argu…
