ChartMimic: Evaluating LMM's Cross-Modal Reasoning Capability via Chart-to-Code Generation

Cheng Yang, Chufan Shi, Yaxin Liu +11

We introduce a new benchmark, ChartMimic, aimed at assessing the visually-grounded code generation capabilities of large multimodal models (LMMs). ChartMimic utilizes information-i…

"Ghost of the past": identifying and resolving privacy leakage from LLM's memory through proactive user interaction

Shuning Zhang, Lyumanshan Ye, Xin Yi +5

Memories, encompassing past inputs in context window and retrieval-augmented generation (RAG), frequently surface during human-LLM interactions, yet users are often unaware of thei…
