Nicholas,

We updated MGIZA++ in the Moses github repository with changes to
support cross-platform operation on Windows. These were not intended to
be only for Windows users and should not affect OSX or Linux. If you ran
across some problems with the updates, please work with Jeroen so it
works properly on all platforms.

Thanks!
Tom

Hi

To be honest, I have not experimented much with the settings. If the
filtering does not work for you, it could be that your training data is
small or out-of-domain, so that the poorly attested phrase pairs are
actually important.

Can you see from looking at the translations what changes when you
filter at default settings? (note that the length drops).

Do you really need this kind of pruning? Maybe histogram pruning, and/or
the compact data structures can reduce the size of your model sufficiently?

cheers - Barry
