jsat.clustering.OPTICS.ExtractionMethod

All Implemented Interfaces:

Serializable, Comparable<OPTICS.ExtractionMethod>

Enclosing class:

OPTICS

public static enum OPTICS.ExtractionMethod
extends Enum<OPTICS.ExtractionMethod>

Enum to indicate which method of extracting clusters should be used on the reachability plot.

Enum Constant Summary

Enum Constants

Enum Constant and Description
THRESHHOLD Forms clusters in the reachability plot by drawing a line across it, and using the separations to mark clusters
THRESHHOLD_FIXUP Forms clusters in the reachability plot by drawing a line across it, and using the separations to mark clusters.
XI_STEEP_ORIGINAL Uses the original clustering method proposed in the OPTICS paper. NOTE: Implementation not yet complete

Method Summary

Modifier and Type	Method and Description
static OPTICS.ExtractionMethod	valueOf(String name) Returns the enum constant of this type with the specified name.
static OPTICS.ExtractionMethod[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

XI_STEEP_ORIGINAL

public static final OPTICS.ExtractionMethod XI_STEEP_ORIGINAL

Uses the original clustering method proposed in the OPTICS paper.
NOTE: Implementation not yet complete

THRESHHOLD

public static final OPTICS.ExtractionMethod THRESHHOLD

Forms clusters in the reachability plot by drawing a line across it, and using the separations to mark clusters

THRESHHOLD_FIXUP

public static final OPTICS.ExtractionMethod THRESHHOLD_FIXUP

Forms clusters in the reachability plot by drawing a line across it, and using the separations to mark clusters. It then de-noises points by checking their nearest neighbors for consensus

Method Detail

values

public static OPTICS.ExtractionMethod[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OPTICS.ExtractionMethod c : OPTICS.ExtractionMethod.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OPTICS.ExtractionMethod valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
