Detailed Description

template<class FeatureGenerator, class Aggregator, class Metric>
struct RealDecisionStumpOracle< FeatureGenerator, Aggregator, Metric >

A base class for training a Real Decision Stump classifier using scalar features Find the threshold and the weight for a RealDecisionStump using different Metric(s) (for example RealAdaBoost or GentleAdaBoost metrics)

Parameters

FeatureGenerator	generates Feature of type FeatureType
Metric	metric used to choose the best feature. RealAdaBoostMetric or GentleAdaBoostMetric.

Note

FeatureType is the type of feature involved in training

PatternType must have a GetWeight() method implemented.

(

ClassifierType &

bestH

)

Return the best h for current data set. This is the real core of this module: test all FeatureType and produce the bestH classifier with the best of them
