English(EN) What Transfers from a VLM Teacher? Comparing Supervision Signals for Visual Document Retrieval

视觉-语言模型通过判断负样本来增强文档检索

研究人员探索了如何利用视觉-语言模型(VLM)来改进视觉文档检索系统。研究发现,除了仅使用 VLM 来丰富正样本外,使用 VLM 来识别和判断困难的负样本可以显著提高检索性能。这种方法通过提炼 VLM 对不相关页面的判断,将 nDCG@5 分数从 55.2 提高到 62.6。研究结果表明,当 VLM 监督应用于负样本时,其效果更佳,而当前标记方法在很大程度上未能解决负样本问题。 AI

影响 通过利用 VLM 进行负样本识别,提高了视觉文档检索系统的有效性。

    VLM教师的哪些信息可以迁移?比较视觉文档检索的监督信号

    Visual document retrievers are trained contrastively: each query is matched to one page labelled relevant - the positive - and pushed away from negatives, pages presumed irrelevant. Recent methods distil a vision-language model (VLM) teacher into the retriever by enriching that p…
