public class EnsembleEstimator extends java.lang.Object implements DistanceBasedIntrinsicDimensionalityEstimator
Ensemble estimator taking the median of three of our best estimators.However, the method-of-moments estimator seems to work best at least on artificial distances - you don't benefit from always choosing the second best, so this ensemble approach does not appear to help.
This is an experimental estimator. Please cite ELKI when using.
