Class GmeansSampling<I extends IInstance>

  • All Implemented Interfaces:
    ai.libs.jaicore.basic.algorithm.IAlgorithm<IDataset<I>,IDataset<I>>, ai.libs.jaicore.basic.Cancelable, ai.libs.jaicore.basic.ILoggingCustomizable, java.lang.Iterable<ai.libs.jaicore.basic.algorithm.events.AlgorithmEvent>, java.util.concurrent.Callable<IDataset<I>>, java.util.Iterator<ai.libs.jaicore.basic.algorithm.events.AlgorithmEvent>


    public class GmeansSampling<I extends IInstance>extends ClusterSampling<I>
    Implementation of a sampling method using gmeans-clustering. This algorithm produces clusters of the given points and checks weather all points in a cluster have the same target Attribute. If yes only the point nearest to the center is added, otherwise the whole cluster is added to the sample.

    Caution: This does ignore the given sample size!
