Well, what's that business mentioned in your mail from January (quoted below), with the backoff being broken, then being broken more, then possibly been fixed - or not?
https://github.com/moses-smt/mosesdecoder/commit/44fec57c535db2df73ccbb1628d8143a9c728c19 I set up a system that was supposed to do backoff with factored generation steps, more or less in the manner of what's described in this paper: Interpolated Backoff for Factored Translation Models, Philipp Koehn and Barry Haddow, AMTA 2012. MIRA tunes all the weights of the backoff models to 0. With exactly the same configuration, this did not happen last year (February 2014). Maybe the [decoding-graph-backoff] setting didn't have any effect prior to some of your code modifications, and the models were actually competing in older setups? Or it's buggy now. I can't really tell. I can show you the two setups if you want. On Thu, 2015-04-16 at 21:34 +0400, Hieu Hoang wrote: > Didn't know it has changed.
