Researchers have introduced EndoCA, a new benchmark designed to assess the consistency of answers in endoscopic visual question answering (VQA) systems. This benchmark evaluates whether complex answers provided by a model align with the atomic answers derived from the same image. The study found that while some models achieve high accuracy on complex questions, their performance on associated atomic questions and overall consistency is significantly lower. To address this, a training-free mechanism called Atomic-Support Reconciliation (ASR) was developed, which uses model-generated atomic answers to revise complex answers or guide selective answering.
