Hi, Is histogram pruning always on? What's the default stack size? Why isn't it listed among the settings on the Syntax Tutorial page?
How is the search and pruning actually done for hierarchical models? When is the histogram pruning done? I've tested with the settings: moses_chart -f trainTreeSyntaxInSourceAndTarget/model/moses.ini < fr-sv.test.fr > fr-sv.test.fr.TreeSyntaxInSourceAndTarget.translated 2> stderrTreeSyntaxInSourceAndTarget.txt I suppose I got the default cube-pruning-pop-limit 1000, but what about the histogram pruning? I've read that the stack size isn't much of a problem when using cube pruning (Advanced Features page). BTW The results are very disappointing. Yours, Per Tunedal PS I've read a lot of books and papers on the subject but got lost in the details. A very simplified explanation with the main steps for the implementation in Moses would be helpful.
