CURV targets visual grounding in chart question answering
The arXiv paper introduces a curriculum framework and CCQA dataset for multimodal chart reasoning.
Why it matters
The paper addresses a persistent weakness in multimodal large language models: reasoning chains that are not reliably grounded in visual evidence. Better chart grounding could improve AI systems used for data analysis, scientific documents and business reporting.
The key points
- 1.CURV trains chart reasoning through a staged curriculum.
- 2.CCQA covers multiple chart types and reasoning patterns.
- 3.Authors report up to 20.50% gains over baselines.
Researchers proposed CURV, a curriculum learning framework for chart question answering that reformulates the task as multi-step visual grounded reasoning. The work also introduces CCQA, a three-level curriculum dataset generated across chart types and reasoning patterns, progressing from single-operation tasks to complex multi-chart compositional tasks. The authors report that CURV improves over baselines by up to 20.50% and generalizes to real-world chart question answering settings.
