Class EnsembleEstimator

java.lang.Object

de.lmu.ifi.dbs.elki.math.statistics.intrinsicdimensionality.EnsembleEstimator

All Implemented Interfaces:

IntrinsicDimensionalityEstimator

public class EnsembleEstimator
extends java.lang.Object
implements IntrinsicDimensionalityEstimator

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.
