['System', 'MT05', 'MT06', 'MT08', 'Avg']
The baseline NMT significantly outperforms the open-source Dl4mt by 2.43 BLEU points, indicating the baseline is strong. Our proposed M-RefNet and B-RefNet improve the baseline NMT by 2.34 and 2.69 BLEU respectively and up to 2.90 and 3.17 BLEU on NIST MT06, which confirms the effectiveness of our proposed reference networks. Overall, B-RefNet achieves the best performance over all test sets
