Deep Blue Sonics' Submission to IWSLT 2020 Open Domain Translation Task

摘要

We present in this report our submission to IWSLT 2020 Open Domain Translation Task(Ansari et al., 2020). We built a data preprocessing pipeline to efficiently handle large noisy web-crawled corpora, which boosts the BLEU score of a widely used transformer model in this translation task. To tackle the open-domain nature of this task, back-translation (Sennrich et al., 2016) is applied to further improve the translation performance.
