| Challenge: | Open-domain Question Answering models that directly leverage question-answer (QA) pairs show promise in terms of speed and memory compared with conventional models which retrieve and read from text corpora. |
| Approach: | They propose a question-answer (QA)-pair retriever to facilitate improved QA-patch models by introducing Probably Asked Questions (PAQ) they propose QA pair retriever, RePAQ, which preempts and caches test questions, enabling it to match the accuracy of recent retrieve-and-read models, whilst being significantly faster. |
| Outcome: | The proposed model outperforms baseline models by 5% but trails RePAQ by 15% . it can be configured for size (under 500MB) or speed (over 1K questions per second) while retaining high accuracy. |
