vigra::rf::split Namespace Reference

Classes
class	Median
class	RandomSplitOfColumn

Detailed Description

This namespace contains additional Splitfunctors.

The Split functor classes are designed in a modular fashion because new split functors may share a lot of code with existing ones.

ThresholdSplit implements the functionality needed for any split functor, that makes its decision via one dimensional axis-parallel cuts. The Template parameter defines how the split along one dimension is chosen.

The BestGiniOfColumn class chooses a split that minimizes one of the Loss functions supplied (GiniCriterion for classification and LSQLoss for regression). Median chooses the Split in a kD tree fashion.

Currently defined typedefs:

typedef  ThresholdSplit<BestGiniOfColumn<GiniCriterion> >                 GiniSplit;
typedef  ThresholdSplit<BestGiniOfColumn<LSQLoss>, RegressionTag>         RegressionSplit;
typedef  ThresholdSplit<Median> MedianSplit;
