Hi,

Since MT training is non-convex and thus the BLEU score varies, which score
should I use for my system? I trained my system three times using the same
data and obtained the three different scores below. Should I take the
average or the best score?

BLEU = 17.84, 49.1/22.0/12.5/7.5 (BP=1.000, ratio=1.095, hyp_len=3952,
ref_len=3609)
BLEU = 16.51, 48.4/20.7/11.4/6.5 (BP=1.000, ratio=1.093, hyp_len=3945,
ref_len=3609)
BLEU = 15.33, 48.2/20.1/10.3/5.5 (BP=1.000, ratio=1.087, hyp_len=3924,
ref_len=3609)

Thanks,
Hilton
