Structured Attentions for Visual Question Answering

The repository contains the majority of the code to reproduce the experimental results of the paper Structured Attentions for Visual Question Answering on the VQA-1.0 and VQA-2.0 dataset. Currently only the accelerated version of Mean Field is provided, which is used in the VQA 2.0 challenge.

Prerequisites

To reproduce the experimental results,

Clone and compile mxnet, with mxnet@c9e252, cub@89de7ab, dmlc-core@3dfbc6, nnvm@d3558d, ps-lite@acdb69, mshadow@8eb1e0. There has been some modification on optimizers (and others) in later versions of mxnet, and code in this repository has not been adapted yet.
ResNet-152 feature of MS COCO images: extracted with MCB's preprocess code.
Our training question and answer data for VQA2.0: Baidu Pan.

Training from scratch

Set the arguments and run train_VQA.py.

Pretrained models

The best single model accuracy on test-dev of VQA-1.0 and VQA-2.0 with skip-thought vector initialization and Visual Genome training data are 67.19 and 64.78 respectively. Here is the model on VQA-2.0.
