Table 2. BLEU Scores Based on k-grams (k = 2, 3, 4, and 5) for Three Baseline Models (MLE, CVAE, and SeqGAN) and Three Variants of PepGAN (λ = 0, 0.5, and 1)^a.

	MLE	CVAE	SeqGAN	λ = 0	λ = 0.5	λ = 1.0
BLEU-2	0.939	0.975	0.947	0.922	0.938	0.930
BLEU-3	0.711	0.714	0.729	0.759	0.778	0.776
BLEU-4	0.374	0.331	0.388	0.469	0.487	0.493
BLEU-5	0.182	0.149	0.188	0.246	0.257	0.264
average	0.551	0.542	0.563	0.599	0.615	0.616
