Visual question answering (VQA) with knowledge is a task that requires knowledge to answer questions on images/video. This additional requirement of knowledge poses an interesting challenge on top of the classic VQA tasks. Specifically, a system needs to explore external knowledge sources to answer the questions correctly, as well as understanding the visual content.
Representation of videos has been a major research topic for various deep learning applications including visual question answering. This is a challenging problem especially for tasks that involves vision and language and some researchers pointed out that deep neural network-based models mainly use natural language text but not the vision. We propose to use textual representation of videos, in which SOTA models for detection/recognition are used for generating text together with some rules. The results are presented at ECCV 2020.
We also work on question answering on art, which requires high-level understanding of paintings themselves as well as associated knowledge on them.
