it should be possible to substitute another scoring function into MERT, but as far as i'm aware this has not been done (for Moses). it would be good to see this!
(ibm-bleu would be another interesting candidate) and as for the maximum number of features, your mileage will clearly vary according to the amount of data etc; as a rule of thumb i've not seen much using more than say 14 features (unlike our large-scale work, which uses millions of features) Miles 2008/5/8 Jason Katz-Brown <[EMAIL PROTECTED]>: > (I sent this mail once before, but it bounced because one of MIT's > mailman servers filled a disk.
