Protecting Privacy in Multimodal Large Language Models with MLLMU-Bench

NAACL 2025long

Generative models such as Large Language Models (LLM) and Multimodal Large Language models (MLLMs) trained on massive web corpora can memorize and disclose individuals’ confidential and private data, raising legal and ethical concerns. While many previous works have addressed this issue in LLM via m…

PLUG: Leveraging Pivot Language in Cross-Lingual Instruction Tuning

ACL 2024long

Instruction tuning has remarkably advanced large language models (LLMs) in understanding and responding to diverse human instructions. Despite the success in high-resource languages, its application in lower-resource ones faces challenges due to the imbalanced foundational abilities of LLMs across d…

Multi-source Semantic Graph-based Multimodal Sarcasm Explanation Generation

ACL 2023long

Multimodal Sarcasm Explanation (MuSE) is a new yet challenging task, which aims to generate a natural language sentence for a multimodal social post (an image as well as its caption) to explain why it contains sarcasm. Although the existing pioneer study has achieved great success with the BART back…
