Decomposing Complex Questions Makes Multi-Hop QA Easier and More Interpretable (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Multi-hop QA requires the machine to answer complex questions through finding multiple clues and reasoning, and provide explanatory evidence to demonstrate the reasoning process. |
| Approach: | They propose a three-stage framework based on complex question decomposition that decomposes the complex question, then reads the sub-questions and then performs numerical comparison to get the final answer. |
| Outcome: | The proposed framework achieves state-of-the-art in the 2WikiMultiHopQA dataset, with a winning joint F1 score of 53.58 on the leaderboard. |

| Challenge: | Neural Processing Units (NPUs) are critical for AI infrastructure, but their development remains a bottleneck due to vendor-specific Domain-Specific Languages (DSLs). |
| Approach: | They propose a framework for NPU kernel development that bridges the gap in hardware-specific coding . compiler success on complex Level-2 kernels improves from 0% to 95.5%, they say . |
| Outcome: | The proposed framework bridges the gap in hardware-specific coding, showing a near-zero success rate on complex kernels. |
Discriminating between Similar Languages on Imbalanced Conversational Texts (L18-1)
Copied to clipboard
| Challenge: | Empirical results suggest that our system achieves an accuracy of 95.7% on our Uyghur and Kazakh dataset, which is higher than that of the CNN classifier. |
| Approach: | They propose to build a balanced Uyghur and Kazakh corpus and build morphological classifiers to discriminate between the two languages. |
| Outcome: | The proposed system outperforms the champions on both test sets B1 and B2. |
