LLaMA-Excitor: General Instruction Tuning via Indirect Feature Interaction

no code implementations1 Apr 2024 Bo Zou, Chao Yang, Yu Qiao, Chengbin Quan, Youjian Zhao

LLaMA-Excitor ensures a self-adaptive allocation of additional attention to input instructions, thus effectively preserving LLMs' pre-trained knowledge when fine-tuning LLMs on low-quality instruction-following datasets.

VideoDistill: Language-aware Vision Distillation for Video Question Answering

no code implementations1 Apr 2024 Bo Zou, Chao Yang, Yu Qiao, Chengbin Quan, Youjian Zhao

In this paper, we are inspired by the human recognition and learning pattern and propose VideoDistill, a framework with language-aware (i. e., goal-driven) behavior in both vision perception and answer generation process.

Building an Invisible Shield for Your Portrait against Deepfakes

no code implementations22 May 2023 Jiazhi Guan, Tianshu Hu, Hang Zhou, Zhizhi Guo, Lirui Deng, Chengbin Quan, Errui Ding, Youjian Zhao

Unlike authentic images, where the hidden messages can be extracted with precision, manipulating the facial attributes through deepfake techniques can disrupt the decoding process.

Detecting Deepfake by Creating Spatio-Temporal Regularity Disruption

no code implementations21 Jul 2022 Jiazhi Guan, Hang Zhou, Mingming Gong, Errui Ding, Jingdong Wang, Youjian Zhao

Specifically, by carefully examining the spatial and temporal properties, we propose to disrupt a real video through a Pseudo-fake Generator and create a wide range of pseudo-fake videos for training.

CORE: Consistent Representation Learning for Face Forgery Detection

1 code implementation6 Jun 2022 Yunsheng Ni, Depu Meng, Changqian Yu, Chengbin Quan, Dongchun Ren, Youjian Zhao

Specifically, we first capture the different representations with different augmentations, then regularize the cosine distance of the representations to enhance the consistency.
