MED-VRAG: Iterative Multimodal Retrieval-Augmented Generation for Medical Question Answering

A new arXiv paper introduces MED-VRAG, a retrieval-augmented generation approach for medical question answering that works with full document pages rather than only extracted text chunks. Existing medical RAG pipelines typically discard tables, figures, and page layout, so the proposed method retains that visual information and applies retrieval iteratively. The authors argue this multimodal, multi-step design better serves medical QA tasks.

Study Probes How Misleading Context Skews Medical Question Answering

A new arXiv paper investigates why large language models can give wrong medical answers when the context they receive is misleading, even though their standalone medical accuracy is high. The authors analyze the internal mechanisms behind this susceptibility, aiming to explain how flawed context overrides a model's medical knowledge. The work is a revised cross-listing on arXiv and falls under AI and machine learning research.

Study proposes perturbation-sensitive selection for medical QA rationales

A new arXiv paper addresses the scarcity of high-quality rationales in medical question-answering datasets, where answer labels are plentiful but explanations are expensive to validate. The authors reframe the data acquisition problem as deciding which already-labeled questions warrant rationales, using a perturbation-sensitive selection criterion. The approach aims to improve QA robustness by targeting rationale annotation where it has the greatest effect.
