By the way, has anyone played around with fast-align? I heard it would
not affect translation quality, but from what I see for first
experiments I am getting around 2 BLEU points less for en-fr than with
mgiza. It is pretty fast though. Training was bidirectional with "-v -d
-o" options, symmetrization to grow-diag-final. Any pro-tips for
fast-align?
