ONER: Online Experience Replay for Incremental Anomaly Detection

no code implementations • 5 Dec 2024 • Yizhou Jin, Jiahui Zhu, Guodong Wang, Shiwei Li, Jinjin Zhang, Xinyue Liu, Qingjie Liu, Yunhong Wang

Incremental anomaly detection aims to sequentially identify defects in industrial product lines but suffers from catastrophic forgetting, primarily due to knowledge overwriting during parameter updates and feature conflicts between tasks.

Investigating Compositional Challenges in Vision-Language Models for Visual Grounding

1 code implementation • CVPR 2024 • Yunan Zeng, Yan Huang, Jinjin Zhang, Zequn Jie, Zhenhua Chai, Liang Wang

To demonstrate this we propose Attribute Relation and Priority grounding (ARPGrounding) benchmark to test VLMs' compositional reasoning ability on visual grounding tasks.

Exploration and Exploitation of Unlabeled Data for Open-Set Semi-Supervised Learning

no code implementations • 30 Jun 2023 • Ganlong Zhao, Guanbin Li, Yipeng Qin, Jinjin Zhang, Zhenhua Chai, Xiaolin Wei, Liang Lin, Yizhou Yu

In this paper, we address a complex but practical scenario in semi-supervised learning (SSL) named open-set SSL, where unlabeled data contain both in-distribution (ID) and out-of-distribution (OOD) samples.

Representation and Correlation Enhanced Encoder-Decoder Framework for Scene Text Recognition

1 code implementation • 13 Jun 2021 • Mengmeng Cui, Wei Wang, Jinjin Zhang, Liang Wang

However, for the current state-of-the-art(SOTA) methods, there is room for improvement in terms of the efficient usage of local visual and global context information of the input text image, as well as the robust correlation between the scene processing module(encoder) and the text processing module(decoder).
