Question action relevance and editing for visual question answering

Visual Question Answering (VQA) expands on the Turing Test, as it involves the ability to answer questions about visual content. Current efforts in VQA, however, still do not fully consider whether a question about visual content is relevant and if it is not, how to edit it best to make it answerable. Question relevance has only been considered so far at the level of a whole question using binary classification and without the capability to edit a question to make it grounded and intelligible. The only exception to this is our prior research effort into question part relevance that allows for relevance and editing based on object nouns. This paper extends previous work on object relevance to determine the relevance for a question action and leverage this capability to edit an irrelevant question to make it relevant. Practical applications of such a capability include answering biometric-related queries across a set of images, including people and their action (behavioral biometrics). The feasibility of our approach is shown using Context-Collaborative VQA (C2VQA) Action/Relevance/Edit (ARE). Our results show that our proposed approach outperforms all other models for the novel tasks of question action relevance (QAR) and question action editing (QAE) by a significant margin. The ultimate goal for future research is to address full-fledged W5 + type of inquires (What, Where, When, Why, Who, and How) that are grounded to and reference video using both nouns and verbs in a collaborative context-aware fashion.
