Package elki.outlier.meta

Class ExternalDoubleOutlierScore

java.lang.Object

elki.outlier.meta.ExternalDoubleOutlierScore

All Implemented Interfaces:

Algorithm, OutlierAlgorithm

public class ExternalDoubleOutlierScore
extends java.lang.Object
implements OutlierAlgorithm

External outlier detection scores, loading outlier scores from an external file. This class is meant to be able to read the default output of ELKI, i.e. one object per line, with the DBID specified as ID= and the outlier score specified with an algorithm-specific prefix.

Since:

0.4.0
