['[BOLD] Methods', '[BOLD] 900k', '[BOLD] 2.8M']
It is clear that our method outperforms these two methods. Although the concatenation method [Tiedemann2017Neural] can improve document-level NMT over the RNNSearch model [o2017The], it fails to improve the Transformer model. Comparied with the method by Zhang et al. [Zhang2018Improving] that is also based on Transformer, our work outperforms their model by 0.72 and 0.65 BLEU points on the two datasets.
