public HoldOutSubsetEvaluator()
public abstract double evaluateSubset(java.util.BitSet subset, Instances holdOut) throws java.lang.Exception
subset
- a bitset representing the attribute subset to be
evaluated
holdOut
- a set of instances (possibly seperate and distinct
from those use to build/train the evaluator) with which to
evaluate the merit of the subset
public abstract double evaluateSubset(java.util.BitSet subset, Instance holdOut, boolean retrain) throws java.lang.Exception
subset
- a bitset representing the attribute subset to be
evaluated
holdOut
- a single instance (possibly not one of those used to
build/train the evaluator) with which to evaluate the merit of the subset
retrain
- true if the classifier should be retrained with respect
to the new subset before testing on the holdOut instance.
