RobustVisRAG: Causality-Aware Vision-Based Retrieval-Augmented Generation under Visual Degradations

Vision-based Retrieval-Augmented Generation (VisRAG) leverages vision-language models (VLMs) to jointly retrieve relevant visual documents and generate grounded answers based on multimodal evidence. However, existing VisRAG models degrade in performance when visual inputs suffer from distortions suc
