You could fiddle with the mert-moses.pl script (line 73) to limit the range: "I" => [ [ 0.0, 0.0, 0.0 ],], # input lattice scores Or you use the --activate-features option to selectively activate features. > 2) Mert aborts with an error message: > I ran mert with a SL input in a lattice format using the following > command:scripts-20110203-1116/training/mert-moses.pl > --no-filter-phrase-table --decoder-flags '-inputtype 2 -weight-i 0' > en_lattice dev_de moses-cmd/src/moses model/moses_lattice.ini > --working-dir tuning_lattice --rootdir scripts-20110203-1116 > Running this command leads to the following error:Can't use an undefined value as an ARRAY reference at > scripts-20110203-1116/training/mert-moses.pl line 688. mert doesn't use the decoder flags itself. you need to include weight-i in your moses.ini file: [weight-i] 0 hope this helps, Rico _______________________________________________ Moses-support mailing list [email protected] http://mailman.mit.edu/mailman/listinfo/moses-support
