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.
