X-CLIP: End-to-End Multi-grained Contrastive Learning for Video-Text Retrieval

Introduction

The implementation of paper X-CLIP: End-to-End Multi-grained Contrastive Learning for Video-Text Retrieval. Accepted by ACMMM22. By Yiwei Ma, Guohai Xu, Xiaoshuai Sun*, Ming Yan, Ji Zhang, Rongrong Ji.

X-CLIP adopts cross-grained contrastive learning and attention over similarity matrix module to filter out unnecessary information during video-text retrieval. It achieves SOTA results on MSR-VTT, MSVD, LSMDC, DiDeMo, and ActivityNet.
