Deterministic Non-Autoregressive Neural Sequence Modeling by Iterative Refinement
Table 6: BLEU scores on each dataset when using reference length (ref) and predicted target length (pred).

The quality of length prediction has an impact on the overall translation/captioning performance. When using the reference target length (during inference), we consistently observed approximately 1 BLEU score improvement over reported results in the tables and figures across different datasets in the paper (see
