Prefix Embeddings for In-context Machine Translation

Strategies for Adapting Multilingual Pre-training for Domain-Specific Machine Translation

no code implementations AMTA 2022 Neha Verma, Kenton Murray, Kevin Duh

Therefore, in this work, we propose two major fine-tuning strategies: our language-first approach first learns the translation language pair via general bitext, followed by the domain via in-domain bitext, and our domain-first approach first learns the domain via multilingual in-domain bitext, followed by the language pair via language pair-specific in-domain bitext.
