- - com.yahoo.labs.samoa.moa.classifiers.core.driftdetection.ADWIN

All Implemented Interfaces:

MOAObject, Serializable
```
public class ADWIN
extends AbstractMOAObject
```
ADaptive sliding WINdow method. This method is a change detector and estimator. It keeps a variable-length window of recently seen items, with the property that the window has the maximal length statistically consistent with the hypothesis "there has been no change in the average value inside the window".
