A Focused Dynamic Attention Model for Visual Question Answering

no code implementations6 Apr 2016 Ilija Ilievski, Shuicheng Yan, Jiashi Feng

Solving VQA problems requires techniques from both computer vision for understanding the visual contents of a presented image or video, as well as the ones from natural language processing for understanding semantics of the question and generating the answers.
