Few-shot Online Anomaly Detection and Segmentation

no code implementations27 Mar 2024 Shenxing Wei, Xing Wei, Zhiheng Ma, Songlin Dong, Shaochen Zhang, Yihong Gong

Recent research in this domain has emphasized the necessity of a large volume of training data, overlooking the practical scenario where, post-deployment of the model, unlabeled data containing both normal and abnormal samples can be utilized to enhance the model's performance.

Towards Practical Multi-Robot Hybrid Tasks Allocation for Autonomous Cleaning

1 code implementation12 Mar 2023 Yabin Wang, Xiaopeng Hong, Zhiheng Ma, Tiedong Ma, Baoxing Qin, Zhou Su

Task allocation plays a vital role in multi-robot autonomous cleaning systems, where multiple robots work together to clean a large area.

Isolation and Impartial Aggregation: A Paradigm of Incremental Learning without Interference

1 code implementation29 Nov 2022 Yabin Wang, Zhiheng Ma, Zhiwu Huang, YaoWei Wang, Zhou Su, Xiaopeng Hong

To avoid obvious stage learning bottlenecks, we propose a brand-new stage-isolation based incremental learning framework, which leverages a series of stage-isolated classifiers to perform the learning task of each stage without the interference of others.
