Researchers have developed a new framework called "Ground Then Rank" (GTR) to improve Knowledge-Based Visual Question Answering (KB-VQA) performance. This method decouples entity identification from evidence ranking, addressing limitations in existing multi-modal retrieval augmented generation (MM-RAG) approaches. By first prompting a multi-modal large language model (MLLM) to identify high-confidence entities from a candidate list, and then using an off-the-shelf re-ranker for evidence selection, GTR achieves superior results on benchmarks like Encyclopedic-VQA and InfoSeek while reducing computational complexity.
