Detailed Description

template<class Tag>
class vigra::SplitBase< Tag >

Base Class for all SplitFunctors used with the RandomForest class defines the interface used while learning a tree.


Member Function Documentation

void set_external_parameters ( ProblemSpec< T > const &  in)

returns the DecisionTree Node created by SplitBase::findBestSplit() or SplitBase::makeTerminalNode().

Reimplemented in ThresholdSplit< ColumnDecisionFunctor, Tag >.

void reset ( )

resets internal data. Should always be called before calling findBestSplit or makeTerminalNode

int findBestSplit ( MultiArrayView< 2, T, C >  features,
MultiArrayView< 2, T2, C2 >  labels,
Region  region,
ArrayVector< Region >  childs,
Random  randint 
)

findBestSplit has to be re-implemented in derived split functor. The defaut implementation only insures that a CompileTime error is issued if no such method was defined.

int makeTerminalNode ( MultiArrayView< 2, T, C >  features,
MultiArrayView< 2, T2, C2 >  labels,
Region &  region,
Random  randint 
)

Default action for creating a terminal Node. sets the Class probability of the remaining region according to the class histogram
