Table 4.10: Transfer learning with English reused either in source (encoder) or target (decoder). The baselines correspond to training on one corpus only. BLEU scores are always reported for the child language pair. The scores are comparable within lines or whenever the child language pair is the same. The ‡ represents significantly better results.
['Parent', 'Child', 'Balanced Vocabulary', 'Baselines: Only Child', 'Baselines: Only Parent']
All comparisons are with the English on the same translation side for both parent and child. The baselines models are trained exclusively on the child or parent parallel corpus. We do not report parent score on parent testset. Hence warm-start should work for high-resource language pairs.
