摘要:

在联合文本与视觉线索上进行条件推理是一种多模态推理任务,其中文本线索提供先验排列或外部知识,这些信息与视觉内容互补,对于推导出正确答案至关重要。以往利用预训练视觉-语言模型(VLMs)的方法取得了令人瞩目的性能,然而它们缺乏多模态上下文推理能力,尤其是对文本模态信息的处理。为解决这一问题,我们提出了一种名为ModCR的多模态上下文推理方法。与通过跨模态语义对齐进行推理的VLMs不同,ModCR将给定的文本抽象语义和客观图像信息视为前上下文信息,并将其嵌入语言模型中以执行上下文推理。不同于近期在自然语言处理中使用的视觉辅助语言模型,ModCR通过在预训练语言模型中引入图像与文本之间可学习的对齐前缀,融入了语言与视觉之间的多视图语义对齐信息。这使得语言模型非常适合这种基于联合文本与视觉线索的多模态推理场景。我们在两个相应数据集上进行了广泛实验,实验结果表明,与以往强基线相比,性能显著提升(在PMR测试集上精确提升4.8%)。代码链接:\url{https://github.com/YunxinLi/Multimodal-Context-Reasoning}。

英文摘要:

Conditional inference on joint textual and visual clues is a multi-modal reasoning task that textual clues provide prior permutation or external knowledge, which are complementary with visual content and pivotal to deducing the correct option. Previous methods utilizing pretrained vision-language models (VLMs) have achieved impressive performances, yet they show a lack of multimodal context reasoning capability, especially for text-modal information. To address this issue, we propose a Multi-modal Context Reasoning approach, named ModCR. Compared to VLMs performing reasoning via cross modal semantic alignment, it regards the given textual abstract semantic and objective image information as the pre-context information and embeds them into the language model to perform context reasoning. Different from recent vision-aided language models used in natural language processing, ModCR incorporates the multi-view semantic alignment information between language and vision by introducing the learnable alignment prefix between image and text in the pretrained language model. This makes the language model well-suitable for such multi-modal reasoning scenario on joint textual and visual clues. We conduct extensive experiments on two corresponding data sets and experimental results show significantly improved performance (exact gain by 4.8% on PMR test set) compared to previous strong baselines.
