Extended preprint with new experiments arxiv.org/abs/2502.20503 🚨

We identify a key vulnerability of multimodal LLMs: they are easily deceived by misleading charts🫣

This vulnerability opens many doors for future work in automated chart understanding, be sure to check it out!
MLLMs can easily be misled by manipulated charts to produce false answers⚠️📊

We show the extent of this vulnerability and how to fix it by modifying the misleading chart image or replacing it by another modality - 🧵(1/5)

Very excited to share this work which opens new research directions for chart reasoning with LLMs!

We find that, like humans, multimodal LLMs are vulnerable to misleading charts, which severely impairs their chart QA abilities.

We had a blast at this year's @ellis.eu Dagstuhl seminar on "Modular and Agentive LLMs".

Thanks everyone for participating!

Sorry that I’m missing a lot of people. If you’re working on making NLP models more culturally aware, please DM me to be added.
