Class RingsDataStream

java.lang.Object

org.apache.ignite.ml.util.generators.standard.RingsDataStream

All Implemented Interfaces:

DataStreamGenerator

public class RingsDataStream
extends Object
implements DataStreamGenerator

Represents a data stream of vectors produced by family of ring-like distributions around zero blurred by gauss distribution. First ring equals minRadius next ring radius = prev_radius + distanceBetweenRings.
