BayesianNetworkScoringFunctionParameterSet

public BayesianNetworkScoringFunctionParameterSet(AlphabetContainer alphabet,
                                                  int length,
                                                  double ess,
                                                  boolean plugInParameters,
                                                  Measure structureMeasure)
                                           throws Exception

Creates a new BayesianNetworkScoringFunctionParameterSet with pre-defined parameter values.

Parameters:

alphabet - the alphabet of the scoring function boxed in an AlphabetContainer, e.g new AlphabetContainer(new DNAAlphabet())

length - the length of the scoring function, i.e. the length of the sequences this scoring function can handle

ess - the equivalent sample size

plugInParameters - indicates if plug-in parameters, i.e. generative (MAP) parameters shall be used upon initialization

structureMeasure - the Measure used for the structure, e.g. InhomogeneousMarkov

Throws:

Exception - an Exception is thrown if the alphabet or the length are not in the expected range of values

BayesianNetworkScoringFunctionParameterSet

public BayesianNetworkScoringFunctionParameterSet()

Creates a new BayesianNetworkScoringFunctionParameterSet with empty parameter values.

BayesianNetworkScoringFunctionParameterSet

public BayesianNetworkScoringFunctionParameterSet(StringBuffer representation)
                                           throws NonParsableException

Creates a new BayesianNetworkScoringFunctionParameterSet from its XML-representation as defined by the Storable interface.

Parameters:

representation - the XML-code

Throws:

NonParsableException - is thrown if the XML-representation could not be parsed

Method Detail

getEss

public double getEss()

Returns the equivalent samples size defined in this set of parameters.

Returns:

the ess

getPlugInParameters

public boolean getPlugInParameters()

Returns true if plug-in parameters shall be used when creating a BayesianNetworkScoringFunction from this set of parameters.

Returns:

if plug-in parameters shall be used

getMeasure

public Measure getMeasure()
                   throws ParameterSetParser.NotInstantiableException

Returns the structure Measure defined by this set of parameters.

Returns:

the structure measure

Throws:

ParameterSetParser.NotInstantiableException - is thrown if the Measure could not be created from its own InstanceParameterSet

getInstanceComment

public String getInstanceComment()

Description copied from class: InstanceParameterSet

Returns a comment (a textual description) of the class that can be constructed using this ParameterSet.

Specified by:

getInstanceComment in class InstanceParameterSet

Returns:

the comment

getInstanceName

public String getInstanceName()

Description copied from class: InstanceParameterSet

Returns the name of an instance of the class that can be constructed using this ParameterSet.

Specified by:

getInstanceName in class InstanceParameterSet

Returns:

the name

loadParameters

protected void loadParameters()
                       throws Exception

Description copied from class: ParameterSet

Loads the parameters for this ParameterSet. This is in most cases done by calling ParameterSet.initParameterList() or ParameterSet.initParameterList(int) to initialize ParameterSet.parameters and afterwards filling ParameterSet.parameters with instances of subclasses of Parameter.

Specified by:

loadParameters in class ParameterSet

Throws:

Exception - an Exception is thrown if the parameters could not be loaded
