EnsembleEstimator (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

java.lang.Object
- elki.math.statistics.intrinsicdimensionality.EnsembleEstimator

All Implemented Interfaces:

DistanceBasedIntrinsicDimensionalityEstimator, IntrinsicDimensionalityEstimator<java.lang.Object>
```
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.
