Ticket #974 (new task)
Faster threshold search
|Reported by:||janez||Owned by:||janez|
Threshold search could be sped up by implementing special cases of procedures related to the search for binary attributes that would use a pair of double instead of TDistribution.
An alternative is to just avoid TDistribution and use a double * instead. TScoreFeature would have to implement a corresponding method.
Third alternative is to even keep TDistribution but only one (eg. the left one), implement TScoreFeature's operator that would accept the left distribution and the class distribution. This would simplify the threshold search loop (no maintining of the count for the right side) and possibly allow a more efficient computation of scores as well.
