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().

void reset

(

)

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

int findBestSplit	(	MultiArrayView< 2, T, C >	,
		MultiArrayView< 2, T2, C2 >	,
		Region	,
		ArrayVector< Region >	,
		Random
	)

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 >	,
		MultiArrayView< 2, T2, C2 >	,
		Region &	region,
		Random
	)

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