Hi - I'm trying to replicate an experiment done with an older version of Moses, against the latest version. Everything goes identically up to tuning, where the newer version starts with a lower BLEU and runs only 8 as opposed to 19 iterations of MERT, resulting in a lower evaluation score.
Looking more closely at the data files, the phrase tables seem to be slightly different. All of the difference have to do with the third and fourth columns of the phrase tables, as in this example: < " ||| " . ||| (0,1) ||| (0) (0) ||| 0.000201491 0.0130605 0.00038117 0.000751688 2.718 --- > " ||| " . ||| (0) ||| (0) () ||| 0.000201491 0.0130605 0.00038117 0.000751688 2.718 For most of the differences, the older phrase table has more indices, but there are some where the reverse is true. The weights are not different. statmt.org seems to be down at the moment, so I'm not sure what those columns represent. These seem to be the =only= differences between the two versions, in the main (huge) phrase table as well as all the filtered versions. Of course, the MERT code, etc., is presumably different, but I thought I'd ask about this anyway. Does it mean anything? Thanks! - John D.
