Semantic-Constraint Matching Transformer for Weakly Supervised Object Localization

no code implementations4 Sep 2023 Yiwen Cao, Yukun Su, Wenjun Wang, Yanxia Liu, Qingyao Wu

Weakly supervised object localization (WSOL) strives to learn to localize objects with only image-level supervision.

Imbalance-Agnostic Source-Free Domain Adaptation via Avatar Prototype Alignment

no code implementations22 May 2023 Hongbin Lin, Mingkui Tan, Yifan Zhang, Zhen Qiu, Shuaicheng Niu, Dong Liu, Qing Du, Yanxia Liu

To address this issue, we study a more practical SF-UDA task, termed imbalance-agnostic SF-UDA, where the class distributions of both the unseen source domain and unlabeled target domain are unknown and could be arbitrarily skewed.

Prototype-Guided Continual Adaptation for Class-Incremental Unsupervised Domain Adaptation

1 code implementation22 Jul 2022 Hongbin Lin, Yifan Zhang, Zhen Qiu, Shuaicheng Niu, Chuang Gan, Yanxia Liu, Mingkui Tan

2) Prototype-based alignment and replay: based on the identified label prototypes, we align both domains and enforce the model to retain previous knowledge.

Improved Knowledge Distillation via Adversarial Collaboration

no code implementations29 Nov 2021 Zhiqiang Liu, Chengkai Huang, Yanxia Liu

To achieve this goal, a small student model is trained to exploit the knowledge of a large well-trained teacher model.

Semi-Online Knowledge Distillation

1 code implementation23 Nov 2021 Zhiqiang Liu, Yanxia Liu, Chengkai Huang

However, to the best of our knowledge, KD and DML have never been jointly explored in a unified framework to solve the knowledge distillation problem.

Source-free Domain Adaptation via Avatar Prototype Generation and Adaptation

1 code implementation18 Jun 2021 Zhen Qiu, Yifan Zhang, Hongbin Lin, Shuaicheng Niu, Yanxia Liu, Qing Du, Mingkui Tan

(2) prototype adaptation: based on the generated source prototypes and target pseudo labels, we develop a new robust contrastive prototype adaptation strategy to align each pseudo-labeled target data to the corresponding source prototypes.
