- [2023/04/12]: We provide download links for the processed datasets, including MSRVTT, MSVD, ActivityNet Captions, and DiDeMo. (See EMCL-Net)
- [2023/04/10]: Add MSVD, LSMDC, ActivityNet Captions, and DiDeMo datasets (See EMCL-Net).
- [2023/01/12]: Our approach achieves better performance (46.8 -> 48.2 on MSR-VTT dataset) when training with more GPUs (2 -> 8). So we recommend using more GPUs for better performance.
- [2022/12/14]: Add the code of EMCL-Net.
- [2022/11/21]: Release code for reimplementing the experiments in the paper.

Most video-and-language representation learning approaches employ contrastive learning, e.g., CLIP, to project the video and text features into a common latent space according to the semantic similarities of text-video pairs. However, such learned shared latent spaces are not often optimal, and the modality gap between visual and textual representation can not be fully eliminated. In this paper, we propose Expectation-Maximization Contrastive Learning (EMCL) to learn compact video-and-language representations.
