| Challenge: | Question answering (QA) tasks have been posed using a variety of formats . a new study aims to develop specialized QA models that can be used to train QA systems . |
| Approach: | They build a pre-trained question answering model that performs well across 19 QA datasets . they argue that format-specialized models can limit the ability to teach reasoning . |
| Outcome: | a new model that trains on QA datasets performs on par with 8 models trained on individual datasets . a single model that trained on UNIFIEDQA performs well on 19 QA data . |
