no code implementations10 May 2025 Jiayang Liu, Siyuan Liang, Shiqian Zhao, RongCheng Tu, Wenbo Zhou, Xiaochun Cao, DaCheng Tao, Siew Kei Lam

Our approach formulates the prompt generation task as an optimization problem with three key objectives: (1) maximizing the semantic similarity between the input and generated prompts, (2) ensuring that the generated prompts can evade the safety filter of the text-to-video model, and (3) maximizing the semantic similarity between the generated videos and the original input prompts.

Egocentric Video-Language Pretraining @ Ego4D Challenge 2022

1 code implementation4 Jul 2022 Kevin Qinghong Lin, Alex Jinpeng Wang, Mattia Soldan, Michael Wray, Rui Yan, Eric Zhongcong Xu, Difei Gao, RongCheng Tu, Wenzhe Zhao, Weijie Kong, Chengfei Cai, Hongfa Wang, Dima Damen, Bernard Ghanem, Wei Liu, Mike Zheng Shou

In this report, we propose a video-language pretraining (VLP) based solution \cite{kevin2022egovlp} for four Ego4D challenge tasks, including Natural Language Query (NLQ), Moment Query (MQ), Object State Change Classification (OSCC), and PNR Localization (PNR).
