Collecting Cross-Modal Presence-Absence Evidence for Weakly-Supervised Audio-Visual Event Perception

1 code implementation CVPR 2023 Junyu Gao, Mengyuan Chen, Changsheng Xu

We argue that, for an event residing in one modality, the modality itself should provide ample presence evidence of this event, while the other complementary modality is encouraged to afford the absence evidence as a reference signal.

Cascade Evidential Learning for Open-World Weakly-Supervised Temporal Action Localization

no code implementations CVPR 2023 Mengyuan Chen, Junyu Gao, Changsheng Xu

Targeting at recognizing and localizing action instances with only video-level labels during training, Weakly-supervised Temporal Action Localization (WTAL) has achieved significant progress in recent years.

Fine-grained Temporal Contrastive Learning for Weakly-supervised Temporal Action Localization

1 code implementation CVPR 2022 Junyu Gao, Mengyuan Chen, Changsheng Xu

We target at the task of weakly-supervised action localization (WSAL), where only video-level action labels are available during model training.
