Class AddSingleScale

java.lang.Object

de.lmu.ifi.dbs.elki.algorithm.statistics.AddSingleScale

All Implemented Interfaces:

Algorithm, InspectionUtilFrequentlyScanned, Parameterizable

@Description(value="Setup a scaling so that all dimensions are scaled equally in visualization.")
public class AddSingleScale
extends Object
implements Algorithm

Pseudo "algorithm" that computes the global min/max for a relation across all attributes. FIXME: this should become part of relation metadata.
