Reduce creating std::string objects, too. In both ScoreArray
and FeatureArray classes, the private members to track sentence
indices (namely, "m_index") were unnecessarily declared as
std::string, but it's better to directly declare them as 'int'.
Squashed commit of the following:
- Clean up PRO.
- Clean up ScoreStats.
- Clean up ScoreData.
- Clean up ScoreArray.
- Remove unnecessary headers.
- Clean up ScopedVector.
- Clean up Point.
- Clean up PerScorer.
- Clean up Optimizer.
- Clean up MergeScorer.
- Clean up InterpolatedScorer.
- Clean up FileStream.
- Clean up FeatureStats.
- Remove inefficient string concatenation.
- Clean up FeatureData.
- Clean up FeatureArray.
- Clean up Data.
example:
Use --factor "0|2" to use only first and third factor from nbest list and from reference.
If you use interpolated scorer, separate records with comma (e.g. --factor "0|2,1").
- The Scorer and ScoreData objects allocated by the new
operator are now released using the ScopedVector class.
- Add 'virtual' to inherited functions from the Scorer
class.
example: to interpolate BLEU and CDER use --sctype=BLEU,CDER
to specify weights use --scconfig=weights:0.3+0.7
This scorer should replace MergeScorer (which requires mert-moses-multi.pl) soon.
Interpolated scorer is more universal and is used in the same way as other scorers.
