Trivial Transfer Learning for Low-Resource Neural Machine Translation
Table 9: Candidate total length, BLEU n-gram precisions and brevity penalty (BP). The reference length in the matching tokenization was 36062.
['[EMPTY]', 'Length', 'BLEU Components', 'BP']
In the table, we show also individual n-gram precisions and brevity penalty (BP) of BLEU. The longer output clearly helps to reduce the incurred BP but the improvements are also apparent in n-gram precisions. In other words, the observed gain cannot be attributed solely to producing longer outputs.
