Abstract

Performance of Video Question and Answer (VQA) systems relies on capturing key information of both visual images and natural language in the context to generate relevant questions’ answers. However, traditional linear combinations of multimodal features focus only on shallow feature interactions, fall far short of the need of deep feature fusion. Attention mechanisms were used to perform deep fusion, but most of them can only process weight assignment of single-modal information, leading to attention imbalance for different modalities. To address above problems, we propose a novel VQA model based on Triple Multimodal feature Cyclic Fusion (TMCF) and Self-Adaptive Multimodal Balancing Mechanism (SAMB). Our model is designed to enhance complex feature interactions among multimodal features with cross-modal information balancing. In addition, TMCF and SAMB can be used as an extensible plug-in for exploring new feature combinations in the visual image domain. Extensive experiments were conducted on MSVD-QA and MSRVTT-QA datasets. The results confirm the advantages of our approach in handling multimodal tasks. Besides, we also provide analyses for ablation studies to verify the effectiveness of each proposed component.
