Massively Parallel Cross-Lingual Learning in Low-Resource Target Language Translation
Table 4: Effects of adding family labels on BLEU scores with respect to increasing addition of language families. S and G: same as in Table 3. GSl: Germanic, Slavic family with family labels. GRl: Germanic, Romance family with family labels. 3Fl: Germanic, Slavic, Romance family with family labels. 8Fl: all 8 European families together with family labels
['expt', 'S', 'G', 'GSl', 'GRl', '3Fl', '8Fl']
Training on eight language families, we achieve a BLEU score of 43.9 for English-Swedish translation, +9.9 above the Germanic baseline. Indeed, the more families we have, the more helpful it is to distinguish them.
