Effectiveness on Translation Quality. On an average the sub-sentence shows weaker performance by a 3.08 drop in BLEU score (40.39 → 37.31). Similarly, the wait-k model also brings an obvious decrease in translation quality, even with the best wait-15 policy, its performance is still worse than the baseline system, with a 2.15 drop, averagely, in BLEU (40.39 → 38.24). For a machine translation product, a large degradation in translation quality will largely affect the use experience even if it has low latency. Lastly, the discard 6 tokens obtains an impressive result, with an average improvement of 1.76 BLEU score (37.96 → 39.72).
