Researchers have developed DocVAL, a new framework for distilling validated chain-of-thought reasoning from large vision-language models (VLMs) to smaller, more efficient ones. This method specifically targets improving spatial grounding in document visual question answering, a crucial capability for real-world applications. DocVAL employs a rule-based validator to refine training signals and provides pixel-level corrective feedback, leading to significant improvements in localization accuracy on benchmark datasets. AI
