Machine Translation of Restaurant Reviews:New Corpus for Domain Adaptation and Robustness
Table 8: Combination of several robustness or domain adaptation techniques. At test time, we don’t use any tag on news, and use the PE tag on Foursquare-test (when applicable). BT: back-translation. PE: Foursquare-PE. FT: fine-tuning with Foursquare-PE. ⊕: concatenation.
['Model', 'news', 'test']
The natural noise does not have a significant effect on BLEU scores. Back-translation combined with fine-tuning gives the best performance on Foursquare (+4.5 BLEU vs UGC). However, using tags instead of fine-tuning strikes a better balance between general domain and in-domain performance.
