Generating Question Relevant Captions to Aid Visual Question Answering
Jialin Wu, Zeyuan Hu, Raymond J. Mooney · 2019
Visual question answering (VQA) and image captioning require a shared body of general knowledge connecting language and vision.We present a novel approach to improve VQA performance that exploits this connection by jointly generating captions that are targeted to help answer a specific visual question.The model is trained using an existing caption dataset by automatically determining question-relevant captions using an online gradient-based method.Experimental results on the VQA v2 challenge demonstrates that our approach obtains state-of-the-art VQA performance (e.g.68.4% on the Test-standard set using a single model) by simultaneously generating question-relevant captions.
