Package si.ijs.kt.clus.distance.primitive

Class EuclideanDistance

java.lang.Object

si.ijs.kt.clus.distance.ClusDistance

si.ijs.kt.clus.distance.primitive.EuclideanDistance

All Implemented Interfaces:

Serializable

public class EuclideanDistance
extends ClusDistance

EuclideanDistance works on all type of attributes. It takes sqrt of sum over all differences in attributes values. It depends on difference defined in SearchDistance.calcDistanceOnAttr().
