Learning to Compose Neural Networks for Question Answering

NAACL 2016 · Jacob Andreas, Marcus Rohrbach, Trevor Darrell, Dan Klein ·

We describe a question answering model that applies to both images and structured knowledge bases. The model uses natural language strings to automatically assemble neural networks from a collection of composable modules. Parameters for these modules are learned jointly with network-assembly parameters via reinforcement learning, with only (world, question, answer) triples as supervision. Our approach, which we term a dynamic neural model network, achieves state-of-the-art results on benchmark datasets in both visual and structured domains.
