PointSR: Self-Regularized Point Supervision for Drone-View Object Detection

Weizhuo Li, Yue Xi, Wenjing Jia, Zehao Zhang, Fei Li, Xiangzeng Liu +1

CVPR 2025poster

Point-Supervised Object Detection (PSOD) in a discriminative style has recently gained significant attention for its impressive detection performance and cost-effectiveness. However, accurately predicting high-quality pseudo-box labels for drone-view images, which often feature densely packed small…

Self-Supervised Learning for Sleep Stage Classification with Temporal Augmentation and False Negative Suppression

Fangyao Shen, Zehao Zhang, Yong Peng, Hongjie Guo, Lina Chen, Hong Gao

ICASSP 2024accepted

Self-supervised learning has been gaining attention in the field of sleep stage classification. It learns representations with unlabeled electroencephalography (EEG) signals, which alleviates the cost of labeling for specialists. However, most self-supervised approaches assume only the two augmented…
