TempMe: Video Temporal Token Merging for Efficient Text-Video Retrieval

no code implementations2 Sep 2024 Leqi Shen, Tianxiang Hao, Sicheng Zhao, Yifeng Zhang, Pengzhang Liu, Yongjun Bao, Guiguang Ding

In this work, we argue that temporal redundancy significantly contributes to the model's high complexity due to the repeated information in consecutive frames.

Exploring Structured Semantic Prior for Multi Label Recognition with Incomplete Labels

1 code implementation CVPR 2023 Zixuan Ding, Ao Wang, Hui Chen, Qiang Zhang, Pengzhang Liu, Yongjun Bao, Weipeng Yan, Jungong Han

In this paper, we advocate remedying the deficiency of label supervision for the MLR with incomplete labels by deriving a structured semantic prior about the label-to-label correspondence via a semantic prior prompter.

Prompt Tuning with Soft Context Sharing for Vision-Language Models

1 code implementation29 Aug 2022 Kun Ding, Ying Wang, Pengzhang Liu, Qiang Yu, Haojian Zhang, Shiming Xiang, Chunhong Pan

Inspired by the fact that modeling task relationship by multi-task learning can usually boost performance, we propose a novel method SoftCPT (Soft Context Sharing for Prompt Tuning) to tune pre-trained vision-language models on multiple target few-shot tasks jointly.
