java.lang.Object

elki.visualization.visualizers.scatterplot.cluster.EMClusterVisualization

All Implemented Interfaces:

VisualizationProcessor, VisFactory

public class EMClusterVisualization
extends java.lang.Object
implements VisFactory

Visualizer for generating SVG-Elements containing ellipses for first, second and third standard deviation. In more than 2-dimensional data, the class tries to approximate the cluster extends.
