Table 2: BLEU scores for French-to-German with constrained decoding
['[EMPTY]', 'Euelections-dev-2019', 'Newstest-2013', 'Newstest-2019']
The final models are averages of the 4 best checkpoints in terms of BLEU on the validation set. Applying constraints to Euelections-dev-2019 adds 2 BLEU points to the baseline, but this should not be considered as an improvement, since parts of the reference translations were inserted as constraints. We observe that constrained decoding has nearly no impact on the BLEU score for Newstest-2013, and that it even slightly degrades the score for Newstest-2019.
