| Challenge: | k-nearest-neighbor machine translation (kNN-MT) is a state-of-the-art machine translation technique . however, it requires conducting kNN searches for each decoding step, which increases the cost of decoding . |
| Approach: | They propose to move the time-consuming kNN search forward to the preprocessing phase and introduce k Nearest Neighbor Knowledge Distillation (kNN-KD) that trains the base NMT model to directly learn the knowledge of kN. |
| Outcome: | The proposed method improves over the state-of-the-art model while maintaining the same training and decoding speed as the standard model. |
