Researchers have developed SP-DocReader, a novel self-play framework designed to improve optical character recognition (OCR) accuracy in vision-language models. This method specifically targets and corrects residual errors that persist after initial supervised fine-tuning. By employing techniques like Reading Discrepancy Masking and Focused Fidelity Loss, SP-DocReader enhances the precision of OCR modules without altering the frozen backbone, leading to significant reductions in character error rates and improvements in document visual question answering.
