elki.algorithm.statistics.AddUniformScale

All Implemented Interfaces:

Algorithm

@Description("Setup a scaling so that all dimensions have the same value range.")
public class AddUniformScale
extends java.lang.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.
