void | set_external_parameters (ProblemSpec< T > const &in) |
Base Class for all SplitFunctors used with the RandomForest class defines the interface used while learning a tree.
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

) |
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
