摘要:

预先训练的语言模型在需要理解现实世界中日常物品的属性(例如外观,可测量的数量)和可供性的任务中仍然远远不能达到人类的表现,因为文本由于报告偏差而缺乏这些信息。在这项工作中,我们研究是否整合视觉知识到一个语言模型可以填补空白。我们研究了两种类型的知识转移:(1)文本知识转移使用图像标题,可能包含丰富的视觉知识和(2)跨模态知识转移使用图像和标题与视觉语言训练目标。在5个可能需要视觉知识来解决问题的下游任务上,我们对所提出的目标进行了广泛的实证比较。我们的实验表明,视觉知识转移可以提高性能,在低资源和完全监督的设置。

英文摘要:

Pre-trained language models are still far from human performance in tasks that need understanding of properties (e.g. appearance, measurable quantity) and affordances of everyday objects in the real world since the text lacks such information due to reporting bias. In this work, we study whether integrating visual knowledge into a language model can fill the gap. We investigate two types of knowledge transfer: (1) text knowledge transfer using image captions that may contain enriched visual knowledge and (2) cross-modal knowledge transfer using both images and captions with vision-language training objectives. On 5 downstream tasks that may need visual knowledge to solve the problem, we perform extensive empirical comparisons over the presented objectives. Our experiments show that visual knowledge transfer can improve performance in both low-resource and fully supervised settings.
