Layerwise Optimization by Gradient Decomposition for Continual Learning

no code implementations CVPR 2021 Shixiang Tang, Dapeng Chen, Jinguo Zhu, Shijie Yu, Wanli Ouyang

The gradient for update should be close to the gradient of the new task, consistent with the gradients shared by all old tasks, and orthogonal to the space spanned by the gradients specific to the old tasks.

Neighbourhood-guided Feature Reconstruction for Occluded Person Re-Identification

no code implementations16 May 2021 Shijie Yu, Dapeng Chen, Rui Zhao, Haobin Chen, Yu Qiao

Person images captured by surveillance cameras are often occluded by various obstacles, which lead to defective feature representation and harm person re-identification (Re-ID) performance.

Complementary Relation Contrastive Distillation

1 code implementation CVPR 2021 Jinguo Zhu, Shixiang Tang, Dapeng Chen, Shijie Yu, Yakun Liu, Aijun Yang, Mingzhe Rong, Xiaohua Wang

Specifically, we estimate the mutual relation in an anchor-based way and distill the anchor-student relation under the supervision of its corresponding anchor-teacher relation.

Improved Mutual Mean-Teaching for Unsupervised Domain Adaptive Re-ID

2 code implementations24 Aug 2020 Yixiao Ge, Shijie Yu, Dapeng Chen

SDA, a domain-translation-based framework, focuses on carefully translating the source-domain images to the target domain.

COCAS: A Large-Scale Clothes Changing Person Dataset for Re-identification

no code implementations CVPR 2020 Shijie Yu, Shihua Li, Dapeng Chen, Rui Zhao, Junjie Yan, Yu Qiao

To address the clothes changing person re-id problem, we construct a novel large-scale re-id benchmark named ClOthes ChAnging Person Set (COCAS), which provides multiple images of the same identity with different clothes.
