5.2 Manual Analysis

  1. What did manual analysis show about subword NMT outputs?
    Subword systems learned compounding and transliteration, translating “health research institutes” correctly even with odd segmentations like Forsch|ungsinstitu|ten. Errors came from data sparseness (asinine) and inconsistent source/target segmentations, which joint BPE reduced.
