Ideas
-----
* *MULTIPARTITE* ranking (1 vs all, cluster model/score)
* *REMEMBER* sampled translations (merge)
* *SELECT* iteration with highest (_real_) BLEU?
* *GENERATED* data? (perfect translation in kbest)
* *CACHING* (ngrams for scoring)
* hadoop *PIPES* imlementation
* *ITERATION* variants (shuffle resulting weights, re-iterate)
* *MORE THAN ONE* reference for BLEU?
* *RANDOM RESTARTS*
* use separate TEST SET for each shard
Uncertain, known bugs, problems
-------------------------------
* cdec kbest vs 1best (no -k param), rescoring (ref?)? => ok(?)
* no sparse vector in decoder => ok/fixed
* PhraseModel_* features (0..99 seem to be generated, why 99?)
* flex scanner jams on malicious input, we could skip that
* input/grammar caching (strings, files)
FIXME
-----
* merge with cdec master
