摘要:

尽管视觉问答(VQA)模型最近取得了相当大的进展,但不一致或矛盾的答案继续对其真正的推理能力产生怀疑。然而,大多数提出的方法使用间接策略或强假设对问题和答案,以加强模型的一致性。相反,我们提出了一种新的策略,旨在通过直接减少逻辑不一致来提高模型性能。为此,我们引入了一个新的一致性损失术语,该术语可以被广泛的VQA模型使用,并且依赖于知道问题和答案对之间的逻辑关系。虽然这样的信息通常是不可用的VQA数据集,我们建议推断这些逻辑关系,使用一个专用的语言模型,并使用这些在我们提出的一致性损失函数。我们在VQA Introspect和DME数据集上进行了广泛的实验,并表明我们的方法为最先进的VQA模型带来了改进,同时在不同的架构和设置中具有鲁棒性。

英文摘要:

Despite considerable recent progress in Visual Question Answering (VQA) models, inconsistent or contradictory answers continue to cast doubt on their true reasoning capabilities. However, most proposed methods use indirect strategies or strong assumptions on pairs of questions and answers to enforce model consistency. Instead, we propose a novel strategy intended to improve model performance by directly reducing logical inconsistencies. To do this, we introduce a new consistency loss term that can be used by a wide range of the VQA models and which relies on knowing the logical relation between pairs of questions and answers. While such information is typically not available in VQA datasets, we propose to infer these logical relations using a dedicated language model and use these in our proposed consistency loss function. We conduct extensive experiments on the VQA Introspect and DME datasets and show that our method brings improvements to state-of-the-art VQA models, while being robust across different architectures and settings.
