Decorate the Newcomers: Visual Domain Prompt for Continual Test Time Adaptation

no code implementations8 Dec 2022 Yulu Gan, Yan Bai, Yihang Lou, Xianzheng Ma, Renrui Zhang, Nian Shi, Lin Luo

Since pseudo labels are noisy and unreliable, these methods suffer from catastrophic forgetting and error accumulation when dealing with dynamic data distributions.

Bayesian Evidential Learning for Few-Shot Classification

no code implementations19 Jul 2022 Xiongkun Linghu, Yan Bai, Yihang Lou, Shengsen Wu, Jinze Li, Jianzhong He, Tao Bai

Few-Shot Classification(FSC) aims to generalize from base classes to novel classes given very limited labeled samples, which is an important step on the path toward human-like machine learning.

Memory-Based Label-Text Tuning for Few-Shot Class-Incremental Learning

no code implementations3 Jul 2022 Jinze Li, Yan Bai, Yihang Lou, Xiongkun Linghu, Jianzhong He, Shaoyun Xu, Tao Bai

The difficulties are that training on a sequence of limited data from new tasks leads to severe overfitting issues and causes the well-known catastrophic forgetting problem.

Switchable Representation Learning Framework with Self-compatibility

no code implementations CVPR 2023 Shengsen Wu, Yan Bai, Yihang Lou, Xiongkun Linghu, Jianzhong He, Ling-Yu Duan

Existing research mainly focuses on the one-to-one compatible paradigm, which is limited in learning compatibility among multiple models.

Geometric Anchor Correspondence Mining With Uncertainty Modeling for Universal Domain Adaptation

no code implementations CVPR 2022 Liang Chen, Yihang Lou, Jianzhong He, Tao Bai, Minghua Deng

Therefore, in this paper, we propose a Geometric anchor-guided Adversarial and conTrastive learning framework with uncErtainty modeling called GATE to alleviate these issues.

Neighborhood Consensus Contrastive Learning for Backward-Compatible Representation

no code implementations7 Aug 2021 Shengsen Wu, Liang Chen, Yihang Lou, Yan Bai, Tao Bai, Minghua Deng, Lingyu Duan

Therefore, backward-compatible representation is proposed to enable "new" features to be compared with "old" features directly, which means that the database is active when there are both "new" and "old" features in it.

Dual-Tuning: Joint Prototype Transfer and Structure Regularization for Compatible Feature Learning

1 code implementation6 Aug 2021 Yan Bai, Jile Jiao, Shengsen Wu, Yihang Lou, Jun Liu, Xuetao Feng, Ling-Yu Duan

It is a heavy workload to re-extract features of the whole database every time. Feature compatibility enables the learned new visual features to be directly compared with the old features stored in the database.

Towards Digital Retina in Smart Cities: A Model Generation, Utilization and Communication Paradigm

1 code implementation31 Jul 2019 Yihang Lou, Ling-Yu Duan, Yong Luo, Ziqian Chen, Tongliang Liu, Shiqi Wang, Wen Gao

The digital retina in smart cities is to select what the City Eye tells the City Brain, and convert the acquired visual data from front-end visual sensors to features in an intelligent sensing manner.

VERI-Wild: A Large Dataset and a New Method for Vehicle Re-Identification in the Wild

no code implementations CVPR 2019 Yihang Lou, Yan Bai, Jun Liu, Shiqi Wang, Ling-Yu Duan

To promote the research of vehicle ReID in the wild, we collect a new dataset called VERI-Wild with the following distinct features: 1) The vehicle images are captured by a large surveillance system containing 174 cameras covering a large urban district (more than 200km^2) The camera network continuously captures vehicles for 24 hours in each day and lasts for 1 month.
