Domain Adaptation of Neural Machine Translation by Lexicon Induction
Table 5: 100% successful word translation examples from the output of the IT to Medical adaptation task. The Count column shows the number of occurrences of word pairs in the pseudo-in-domain training set.
['Type', 'Word Pair', 'Count']
In this section, we explore exactly what types of words each method improves on. We randomly pick some in-domain unseen word pairs which are translated 100% correctly in the translation outputs of systems trained with each method. We also count these word pairs’ occurrences in the pseudo-in-domain training set.
