## 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.
