Despite much progress in neural models for joint vision and language understanding, current models are largely opaque and non-compositional. Many language tasks are inherently compositional, and can be solved by decomposing them into modular sub-problems. I will describe End-to End Module Networks (N2NMNs), which learn to answer questions about images by learning to decompose the question into subtasks, implemented as neural network modules. Experimental results show that N2NMNs achieve better accuracy than state-of-the-art attentional approaches, while discovering interpretable network architectures specialized for each question. I will also talk about our recent work on dense video captioning, and describe an end-to-end network that localizes activities in a long video and generates captions to describe each detected activity.
