MedFabric and EtHER: A Data-Centric Framework for Word-Level Fabrication Generation and Detection in Medical LLMs
This paper introduces MedFabric, a data-centric pipeline to generate realistic and word-level fabrications in medical LLMs, addressing shortcomings in existing datasets. It also presents ETHER, a modular word-level fabrication detector that integrates various techniques to enhance factual evaluation.
