Weakly-Supervised Text-driven Contrastive Learning for Facial Behavior Understanding

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Taoyue Wang, Xiaotian Li, Huiyuan Yang, Lijun Yin | Summary: Contrastive learning has shown promising potential for learning robust representations by utilizing unlabeled data. However, constructing effective positive-negative pairs for contrastive learning on facial behavior datasets remains challenging. This is because such pairs inevitably encode […]
