Researchers have developed GRAIL (Gap-aware Retrieval via Adaptive Implicit Localization), a novel retrieval framework designed to improve multimodal multi-hop question answering. GRAIL addresses the issue of semantic anchoring in conventional iterative retrieval systems, which can lead to redundant evidence retrieval. By performing implicit query rewriting at the embedding level and employing context-subtractive query steering, GRAIL enhances compositional cross-modal reasoning. The framework achieved a significant 40.3% macro-averaged performance gain on the MultimodalQA benchmark. AI
