java.lang.Object

ai.libs.jaicore.ml.rqp.AbstractAugmentedSpaceSampler

ai.libs.jaicore.ml.rqp.KNNAugSpaceSampler

All Implemented Interfaces:

IAugmentedSpaceSampler

public class KNNAugSpaceSampler
extends AbstractAugmentedSpaceSampler

Samples interval-valued data from a dataset of precise points. First chooses one point uniformly at random and then generates a point in the interval-valued augmented space from it and its (exact) K nearest neighbors according to euclidean distance on the attributes, excluding the class, which is assumed to be the last attribute.
