Hello everyone, I'm having trouble understanding the -distortion-file parameters that are passed into Moses; it's reported that Moses accepts:
> -distortion-file: source factors (0 if table independent of source), target factors, location of the factorized/lexicalized reordering tables Can someone please further explain what each of these correspond to? For example, having searched through Moses' support mailing list, I see an example whereby someone had passed: > -distortion-file 0-1 wbe-msd-bidirectional-fe-allff 6 /home/meirong-moses/fac-sur+pos+stem/model/reordering-table.0-1.wbe-msd-bidirectional-fe Question 1/Param 1: Do the source factors have to sum to 1 and can be any double (e.g., .4-.6 would be valid?) Question 2/Param 2: This is the base filename that corresponds to the output of processLexicalTable.exe? Question 3/Param 3: 6? This is an example of a target factor? It seems different than the source factor example of 0-1. Question 4/Param 4: What is this file? Is it the base filename that corresponds to the output of processLexicalTable, or maybe it's the lexical reordering scoring table (i.e., the output of having run scripts/training/lexical-reordering/score.cpp?) Any other insights and comments would be much appreciated. Thanks! -- Chris Tanner
