TencentFmRD Neural Machine Translation for WMT18

2018-10-01 · WS 2018 10 · Bojie Hu, Ambyer Han, Shen Huang

This paper describes the Neural Machine Translation (NMT) system of TencentFmRD for Chinese↔English news translation tasks of WMT 2018. Our systems are neural machine translation systems trained with our original system TenTrans. TenTrans is an improved NMT system based on Transformer self-attention mechanism. In addition to the basic settings of Transformer training, TenTrans uses multi-model fusion techniques, multiple features reranking, different segmentation models and joint learning. Finally, we adopt some data selection strategies to fine-tune the trained system and achieve a stable performance improvement. Our Chinese→English system achieved the second best BLEU scores and fourth best cased BLEU scores among all WMT18 submitted systems.

Automatic Classification of Human Translation and Machine Translation: A Study from the Perspective of Lexical Diversity

2021-05-10 · MoTra (NoDaLiDa) 2021 5 · Yingxue Fu, Mark-Jan Nederhof

By using a trigram model and fine-tuning a pretrained BERT model for sequence classification, we show that machine translation and human translation can be classified with an accuracy above chance level, which suggests t…
