  • TLDR:This work presents DistilVDR, a 524M end-to-end VDR system distilled bilaterally from a single 8B vision-language teacher under a pointwise cosine alignment loss and matches VDR's text-query and image-document input asymmetry with an asymmetric encoder-only student that concentrates visual capacity on the document side and keeps the query side at 70M parameters.

  • TLDR中文:本文提出 DistilVDR,一个 524M 的端到端 VDR 系统,通过逐点余弦对齐损失从一个 8B 视觉-语言教师模型进行双向蒸馏,并以非对称的纯编码器学生模型匹配 VDR 的文本查询与图像-文档输入不对称性,将视觉容量集中于文档端,查询端保持 70M 参数。
