Hi all, I tried to use MERT with the --pairwise-ranked option but the length parameter seems to be strangely tuned : If I take the weights obtained with PRO and use them on the test set I get a bad BLEU score and bad length ratio (0.96...).
I would like to combine PRO with line MERT : - I tried to use the option --pro-starting-point. When I enter this option before --pairwise-ranked on the command line, then the weights and log files I obtain look exactly like tuning with --pairwise-ranked only -When I use the option --pro-starting-point alone then I get very different feature weights and log files then when using --pro-starting-point with --pairwise-ranked. Does someone know if I am using the right option? Thanks a lot for any answer! Cheers, Fabienne
