Towards Demystifying the Generalization Behaviors When Neural Collapse Emerges

no code implementations12 Oct 2023 Peifeng Gao, Qianqian Xu, Yibo Yang, Peisong Wen, Huiyang Shao, Zhiyong Yang, Bernard Ghanem, Qingming Huang

While there have been extensive studies on optimization characteristics showing the global optimality of neural collapse, little research has been done on the generalization behaviors during the occurrence of NC.

AUC-Oriented Domain Adaptation: From Theory to Algorithm

1 code implementation TPAMI 2023 Zhiyong Yang, Qianqian Xu, Shilong Bao, Peisong Wen, Xiaochun Cao, Qingming Huang

We propose a new result that not only addresses the interdependency issue but also brings a much sharper bound with weaker assumptions about the loss function.

A Study of Neural Collapse Phenomenon: Grassmannian Frame, Symmetry and Generalization

no code implementations18 Apr 2023 Peifeng Gao, Qianqian Xu, Peisong Wen, Huiyang Shao, Zhiyong Yang, Qingming Huang

Out of curiosity about the symmetry of Grassmannian Frame, we conduct experiments to explore if models with different Grassmannian Frames have different performance.

Building Bridge Across the Time: Disruption and Restoration of Murals In the Wild

no code implementations ICCV 2023 Huiyang Shao, Qianqian Xu, Peisong Wen, Peifeng Gao, Zhiyong Yang, Qingming Huang

Finally, experimental results support the effectiveness of the proposed framework in terms of both mural synthesis and restoration.

Dist-PU: Positive-Unlabeled Learning from a Label Distribution Perspective

1 code implementation CVPR 2022 Yunrui Zhao, Qianqian Xu, Yangbangyan Jiang, Peisong Wen, Qingming Huang

Positive-Unlabeled (PU) learning tries to learn binary classifiers from a few labeled positive examples with many unlabeled ones.

When False Positive is Intolerant: End-to-End Optimization with Low FPR for Multipartite Ranking

no code implementations NeurIPS 2021 Peisong Wen, Qianqian Xu, Zhiyong Yang, Yuan He, Qingming Huang

To leverage high performance under low FPRs, we consider an alternative metric for multipartite ranking evaluating the True Positive Rate (TPR) at a given FPR, denoted as TPR@FPR.
