MG$^2$-RAG: Multi-Granularity Graph for Multimodal Retrieval-Augmented Generation
Apr 8, 2026arXiv Information Retrieval
Event Summary
arXiv:2604.04969v1 Announce Type: new Abstract: Retrieval-Augmented Generation (RAG) mitigates hallucinations in Multimodal Large Language Models (MLLMs), yet existing systems struggle with complex cross-modal reasoning. Flat vector retrieval often ignores structural dependencies, while current grap
