Factor Graph Attention
Table 3: Performance of discriminative models on VisDial v1.0 test-std. Higher is better for MRR and recall@k, while lower is better for mean rank and NDCG. (*) denotes use of external knowledge.

Our submission to the challenge significantly improved all metrics except for NDCG. We report our results in Tab. While the challenge did allow use of any external resources to improve the model, we only changed our approach to use an ensemble of 5 trained Factor Graph Attention models which were initialized randomly. These features are expensive to extract, and use external detector information.
