Learn Suspected Anomalies from Event Prompts for Video Anomaly Detection

no code implementations2 Mar 2024 Chenchen Tao, Chong Wang, Yuexian Zou, Xiaohao Peng, Jiafei Wu, Jiangbo Qian

Most models for weakly supervised video anomaly detection (WS-VAD) rely on multiple instance learning, aiming to distinguish normal and abnormal snippets without specifying the type of anomaly.

Dynamic Relevance Learning for Few-Shot Object Detection

1 code implementation4 Aug 2021 Weijie Liu, Chong Wang, Haohe Li, Shenghao Yu, Jiafei Wu

By adjusting the prediction distribution of the base detector using the output of this GCN, the proposed model serves as a hard auxiliary classification task, which guides the detector to improve the class representation implicitly.
