Semi-Autoregressive Neural Machine Translation (D18-1)
Copied to clipboard
| Challenge: | Existing approaches to neural machine translation are typically autoregressive but suffer from low parallelizability and thus slow at decoding long sequences. |
| Approach: | They propose a semi-autoregressive Transformer model for fast sequence generation that keeps the autoregressive property in global but relieves in local . |
| Outcome: | The proposed model achieves 5.58 speedup while maintaining 88% translation quality, significantly better than previous non-autoregressive methods. |
