EPSILON_ID
public static final OptionID EPSILON_ID
Parameter to specify the maximum distance between two vectors with equal preference vectors before considering them as parallel, must be a double equal to or greater than 0.
-
ALPHA_ID
public static final OptionID ALPHA_ID
The maximum absolute variance along a coordinate axis. Must be in the range of [0.0, 1.0).
-
DEFAULT_ALPHA
public static final double DEFAULT_ALPHA
The default value for alpha.- See Also:
- Constant Field Values
-
K_ID
public static final OptionID K_ID
The number of nearest neighbors considered to determine the preference vector. If this value is not defined, k is set to three times of the dimensionality of the database objects.
-
alpha
protected double alpha
The maximum absolute variance along a coordinate axis.
-
k
protected int k
The number of nearest neighbors considered to determine the preference vector.

configure
public void configure(Parameterization config)
Description copied from interface:Parameterizer
Configure the class.Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.
- Specified by:
configure
in interfaceParameterizer
- Parameters:
config
- Parameterization
-
make
public HiSC make()
Description copied from interface:Parameterizer
Make an instance after successful configuration.Note: your class should return the exact type, only this very broad interface should use
Object
as return type.- Specified by:
make
in interfaceParameterizer
- Returns:
- a new instance
