摘要:

给定问题-图像输入,视觉常识推理(VCR)模型可以预测答案及相应理由,这需要来自真实世界的推理能力。VCR任务要求利用多源信息,学习不同层次的理解和广泛的常识知识,是一项认知级场景理解任务。VCR任务因其广泛的应用而引起了研究者的兴趣,包括视觉问答、自动驾驶车辆系统和临床决策支持。以往解决VCR任务的方法通常依赖预训练或利用具有长依赖关系编码模型的记忆。然而,这些方法存在泛化能力不足和在长序列中丢失信息的问题。在本文中,我们提出了一种基于并行注意力的认知VCR网络PAVCR,它高效地融合视觉-文本信息,并并行编码语义信息,使模型能够捕获丰富的信息以进行认知级推理。大量实验表明,所提出的模型在基准VCR数据集上比现有方法有显著改进。此外,所提出的模型为视觉常识推理提供了直观的解释。

英文摘要:

Given a question-image input, the Visual Commonsense Reasoning (VCR) model can predict an answer with the corresponding rationale, which requires inference ability from the real world. The VCR task, which calls for exploiting the multi-source information as well as learning different levels of understanding and extensive commonsense knowledge, is a cognition-level scene understanding task. The VCR task has aroused researchers' interest due to its wide range of applications, including visual question answering, automated vehicle systems, and clinical decision support. Previous approaches to solving the VCR task generally rely on pre-training or exploiting memory with long dependency relationship encoded models. However, these approaches suffer from a lack of generalizability and losing information in long sequences. In this paper, we propose a parallel attention-based cognitive VCR network PAVCR, which fuses visual-textual information efficiently and encodes semantic information in parallel to enable the model to capture rich information for cognition-level inference. Extensive experiments show that the proposed model yields significant improvements over existing methods on the benchmark VCR dataset. Moreover, the proposed model provides intuitive interpretation into visual commonsense reasoning.
