Adaptive Knowledge Sharing in Multi-Task Learning: Improving Low-Resource Neural Machine Translation (P18-2)
Copied to clipboard
| Challenge: | Neural Machine Translation (NMT) requires large amounts of bilingual data to learn a translation model with reasonable quality. |
| Approach: | They propose to extend recurrent units with multiple "blocks" along with a trainable "routing network" this allows for adaptive collaboration by dynamic sharing of blocks conditioned on the task at hand, input, and model state. |
| Outcome: | Empirical evaluations of two low-resource translation tasks show +1 BLEU score improvements compared to strong baselines. |
