Paper Presentation

Paper Learning to Reason: End-to-End Module Networks for Visual Question Answering by Hu et al. is trying to tackle problem of question answering. As questions are inherently compositional, authors argue that they can be answered easier if decomposed into modular sub-problems. They propose End-to-End Module Networks, which learn to reason by directly predicting instance-specific network layouts without the aid of a parser.
