针对视觉常识推理中先验知识与泛化不足的问题,提出基于动态工作记忆的认知VCR网络,在VCR基准上显著提升性能并提供直观解释。

摘要:

视觉常识推理(Visual Commonsense Reasoning,VCR)在给定问题-图像输入的情况下,预测答案及相应理由。VCR是近期提出的一种视觉场景理解任务,具有广泛应用,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,或利用结合长依赖关系编码模型的记忆。然而,这些方法存在泛化能力和先验知识不足的问题。本文提出一种基于动态工作记忆的认知VCR网络,该网络存储句子之间积累的常识,从而为推理提供先验知识。大量实验表明,所提出模型在基准VCR数据集上相较现有方法取得显著提升。此外,该模型为视觉常识推理提供了直观解释。我们机制的Python实现已公开发布于https://github.com/tanjatang/DMVCR。

英文摘要:

Visual Commonsense Reasoning (VCR) predicts an answer with corresponding rationale, given a question-image input. VCR is a recently introduced visual scene understanding task with a 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 prior knowledge. In this paper we propose a dynamic working memory based cognitive VCR network, which stores accumulated commonsense between sentences to provide prior knowledge for 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. A Python implementation of our mechanism is publicly available at https://github.com/tanjatang/DMVCR
