Revisiting AUC-oriented Adversarial Training with Loss-Agnostic Perturbations

2 code implementations TPAMI 2023 Zhiyong Yang, Qianqian Xu, Wenzheng Hou, Shilong Bao, Yuan He, Xiaochun Cao, Qingming Huang

On top of this, we can show that: 1) Under mild conditions, AdAUC can be optimized equivalently with score-based or instance-wise-loss-based perturbations, which is compatible with most of the popular adversarial example generation methods.

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.

The Minority Matters: A Diversity-Promoting Collaborative Metric Learning Algorithm

1 code implementation NeurIPS 2023 Shilong Bao, Qianqian Xu, Zhiyong Yang, Yuan He, Xiaochun Cao, Qingming Huang

Collaborative Metric Learning (CML) has recently emerged as a popular method in recommendation systems (RS), closing the gap between metric learning and Collaborative Filtering.

AdAUC: End-to-end Adversarial AUC Optimization Against Long-tail Problems

no code implementations ICML 2022 Wenzheng Hou, Qianqian Xu, Zhiyong Yang, Shilong Bao, Yuan He, Qingming Huang

Our analysis differs from the existing studies since the algorithm is asked to generate adversarial examples by calculating the gradient of a min-max problem.

Optimizing Two-way Partial AUC with an End-to-end Framework

1 code implementation TPAMI 2022 Zhiyong Yang, Qianqian Xu, Shilong Bao, Yuan He, Xiaochun Cao, Qingming Huang

The critical challenge along this course lies in the difficulty of performing gradient-based optimization with end-to-end stochastic training, even with a proper choice of surrogate loss.

When All We Need is a Piece of the Pie: A Generic Framework for Optimizing Two-way Partial AUC.

1 code implementation ICML 2021 Zhiyong Yang, Qianqian Xu, Shilong Bao, Yuan He, Xiaochun Cao, Qingming Huang

The critical challenge along this course lies in the difficulty of performing gradient-based optimization with end-to-end stochastic training, even with a proper choice of surrogate loss.

Collaborative Preference Embedding against Sparse Labels

1 code implementation ACM MM 2019 Shilong Bao, Qianqian Xu, Ke Ma, Zhiyong Yang, Xiaochun Cao, Qingming Huang

From the margin theory point-of-view, we then propose a generalization enhancement scheme for sparse and insufficient labels via optimizing the margin distribution.
