新的无监督框架GTR+推动文本Personensuche搜索

研究人员开发了GTR+,一个用于文本Personensuche搜索(TBPS)的无监督框架,该框架可以根据自然语言描述检索图像,而无需手动标注的图像-文本对。该框架采用分层描述生成过程,首先通过自动问答获取基本属性,然后通过样本间对比增强细节,并通过风格化扩展丰富多样性。为了解决生成文本可能带来的噪声问题,GTR+采用自适应置信度加权检索学习方法,将图像-文本对建模为干净或噪声,以便在训练期间分配适当的权重。此外,该项目还推出了LargeFine-Person,一个专为无监督TBPS预训练设计的大规模数据集,该数据集已在多个基准测试中证明了GTR+和该数据集的有效性和泛化能力。 AI

影响 推动了图像检索的无监督学习技术,可能减少计算机视觉任务中对大型标注数据集的需求。

    无监督文本人物搜索的生成式检索

    arXiv:2609.12965v1 Announce Type: new Abstract: Text-based person search (TBPS) aims to retrieve images of a target person from a large image gallery based on a given natural language description. Most existing methods rely on supervised learning with manually annotated image-tex…
