K_ID
public static final OptionID K_ID
Parameter to specify the number of clusters to find.
-
DELTA_ID
public static final OptionID DELTA_ID
Parameter to specify the termination criterion for maximization of E(M): E(M) - E(M') < em.delta, must be a double equal to or greater than 0.
-
MBW_ID
public static final OptionID MBW_ID
Parameter to specify the termination criterion for kd-tree construction. Stop splitting nodes when the width is smaller then mbw * dataset_width. Must be between 0 and 1.
-
TAU_ID
public static final OptionID TAU_ID
Parameter to specify the pruning criterion during the algorithm. Stop going down the kd-tree when possible weight error e < tau * totalweight. Must be between 0 and 1. Low for precise, high for fast results.

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 KDTreeEM 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
