The IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR) is the annual conference on Computer Vision. CVPR is composed of both the main conference, as well as workshops and other courses, to provide a unique learning experience and networking opportunities in the field of Computer Vision.
CVPR 2022 will take place in a hybrid format, hosting people both virtually and in-person in New Orleans, LA from June 19th - 24th, 2022.

In this paper, we present a hierarchical multi-label representation learning framework that can leverage all available labels and preserve the hierarchical relationship between image classes. We apply a hierarchical penalty to the contrastive loss, and enforce the hierarchy constraint. The loss function is data driven and automatically adapts to arbitrary multi-label structures. Experiments on several datasets show that our relationship-preserving embedding performs well on a variety of tasks, and outperforms the base- line supervised and self-supervised approaches.

In this paper, we propose ALPRO, a new video-and-language representation learning framework which achieves state-of-the-art performance on video-text retrieval and video question answering. ALPRO learns fine-grained alignment between video regions and textual entities via two novel pre-training objectives, video-text contrastive (VTC) and prompting entity modeling (PEM). VTC loss focuses on instance-level video-text alignment while PEM enhances alignments between video regions and text entities. Experiments show that ALPRO outperforms prior works by a significant margin across multiple video-text retrieval and video question answering datasets, while being much more label-efficient.
