ALPHA_THRESHOLD_ID
public static final OptionID ALPHA_THRESHOLD_ID
Parameter for the chi squared test threshold.
-
POISSON_THRESHOLD_ID
public static final OptionID POISSON_THRESHOLD_ID
Parameter for the poisson test threshold.
-
MAX_EM_ITERATIONS_ID
public static final OptionID MAX_EM_ITERATIONS_ID
Maximum number of iterations for the EM step.
-
EM_DELTA_ID
public static final OptionID EM_DELTA_ID
Threshold when to stop EM iterations.
-
MIN_CLUSTER_SIZE_ID
public static final OptionID MIN_CLUSTER_SIZE_ID
Minimum cluster size for noise flagging. (Not existant in the original publication).
-
alpha
protected double alpha
Parameter for the chi squared test threshold. While statistical values such as 0.01 are a good choice, we found the need to modify this parameter in our experiments.
-
poissonThreshold
protected double poissonThreshold
Parameter for the poisson test threshold.
-
maxEmIterations
protected int maxEmIterations
Maximum number of iterations for the EM step.
-
emDelta
protected double emDelta
Threshold when to stop EM iterations.
-
minClusterSize
protected int minClusterSize
Minimum cluster size for noise flagging. (Not existant in the original publication).

Method Detail

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 P3C 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
