Question: HOw does the method perform compared with baselines?
Answer: On the datasets DE-EN, JA-EN, RO-EN, and EN-DE, the baseline achieves 29.79, 21.57, 32.70, and 26.02  BLEU score, respectively. The 1.5-entmax achieves  29.83, 22.13, 33.10, and 25.89 BLEU score, which is a difference of +0.04, +0.56, +0.40, and -0.13 BLEU score versus the baseline. The α-entmax achieves 29.90, 21.74, 32.89, and 26.93 BLEU score, which is a difference of +0.11, +0.17, +0.19, +0.91 BLEU score versus the baseline.
