Eyes Closed, Safety On: Protecting Multimodal LLMs via Image-to-Text Transformation

no code implementations14 Mar 2024 Yunhao Gou, Kai Chen, Zhili Liu, Lanqing Hong, Hang Xu, Zhenguo Li, Dit-yan Yeung, James T. Kwok, Yu Zhang

Multimodal large language models (MLLMs) have shown impressive reasoning abilities, which, however, are also more vulnerable to jailbreak attacks than their LLM predecessors.

Leveraging per Image-Token Consistency for Vision-Language Pre-training

no code implementations CVPR 2023 Yunhao Gou, Tom Ko, Hansi Yang, James Kwok, Yu Zhang, Mingxuan Wang

(2) Under-utilization of the unmasked tokens: CMLM primarily focuses on the masked token but it cannot simultaneously leverage other tokens to learn vision-language associations.

Exploring Hierarchical Graph Representation for Large-Scale Zero-Shot Image Classification

1 code implementation2 Mar 2022 Kai Yi, Xiaoqian Shen, Yunhao Gou, Mohamed Elhoseiny

The main question we address in this paper is how to scale up visual recognition of unseen classes, also known as zero-shot learning, to tens of thousands of categories as in the ImageNet-21K benchmark.
