Unsupervised Evaluation of Out-of-distribution Detection: A Data-centric Perspective

Yuhang Zhang, Weihong Deng, Liang Zheng

Out-of-distribution (OOD) detection methods assume that they have test ground truths, i.e., whether individual test samples are in-distribution (IND) or OOD. However, in the real w…

Adaptive Calibrator Ensemble for Model Calibration under Distribution Shift

Yuli Zou, Weijian Deng, Liang Zheng

Model calibration usually requires optimizing some parameters (e.g., temperature) w.r.t an objective function (e.g., negative log-likelihood). In this paper, we report a plain, imp…

Confidence and Dispersity Speak: Characterising Prediction Matrix for Unsupervised Accuracy Estimation

Weijian Deng, Yumin Suh, Stephen Gould +1

This work aims to assess how well a model performs under distribution shifts without using labels. While recent methods study prediction confidence, this work reports prediction di…

Invertible Attention

Jiajun Zha, Yiran Zhong, Jing Zhang +2

Attention has been proved to be an efficient mechanism to capture long-range dependencies. However, so far it has not been deployed in invertible networks. This is due to the fact…

Positive Sample Propagation along the Audio-Visual Event Line

Jinxing Zhou, Liang Zheng, Yiran Zhong +2

Visual and audio signals often coexist in natural environments, forming audio-visual events (AVEs). Given a video, we aim to localize video segments containing an AVE and identify…
