CRAG-MM-Diagnostics: Enabling Stage-Wise Analysis of Knowledge-Intensive VQA

This work introduces CRAG-MM-Diagnostics, a diagnostic benchmark with stage-wise data annotations that isolate 1) language-based visual grounding, 2) object identification, and 3) knowledge retrieval and reasoning from the KI-VQA pipeline, and proposes a grounded bimodal RAG pipeline that integrates a visual grounding module to crop targets before image retrieval.
