| Challenge: | Question Answering (QA) systems rely on deep neural networks, which are difficult to interpret by humans. |
| Approach: | They propose an interpretable model that provides an explanation infrastructure for comparing models based on saliency maps and graph-based explanations. |
| Outcome: | The proposed methods can be used to compare models based on saliency maps and graph-based explanations. |

| Challenge: | Current approaches to QA models are multi-dataset models, but combining expert agents can yield large performance gains over multi-agent models. |
| Approach: | They extend an online platform for QA research to support three families of multi-agent systems: agent selection, early-fusion of agents, and late-fusion. |
| Outcome: | The proposed model can be compared with multi-dataset models and achieve high inference speed and performance. |
