Method Detail

globalInfo

public String globalInfo()

Returns a string describing this object

Returns:

a description of the classifier suitable for displaying in the explorer/experimenter gui

buildStructure

public void buildStructure(BayesNet bayesNet,
                           Instances instances)
                    throws Exception

Description copied from class: SearchAlgorithm

buildStructure determines the network structure/graph of the network. The default behavior is creating a network where all nodes have the first node as its parent (i.e., a BayesNet that behaves like a naive Bayes classifier). This method can be overridden by derived classes to restrict the class of network structures that are acceptable.

Overrides:

buildStructure in class SearchAlgorithm

Parameters:

bayesNet -

instances - the instances to work with

Throws:

Exception - if attribute from BIF file could not be found

setBIFFile

public void setBIFFile(String sBIFFile)

Set name of network in BIF file to read structure from

Parameters:

sBIFFile - the name of the BIF file

getBIFFile

public String getBIFFile()

Get name of network in BIF file to read structure from

Returns:

BIF file name

listOptions

public Enumeration<Option> listOptions()

Returns an enumeration describing the available options.

Specified by:

listOptions in interface OptionHandler

Overrides:

listOptions in class SearchAlgorithm

Returns:

an enumeration of all the available options.

setOptions

public void setOptions(String[] options)
                throws Exception

Parses a given list of options.

Valid options are:

 -B <BIF File>
  Name of file containing network structure in BIF format
 

Specified by:

setOptions in interface OptionHandler

Overrides:

setOptions in class SearchAlgorithm

Parameters:

options - the list of options as an array of strings

Throws:

Exception - if an option is not supported

getOptions

public String[] getOptions()

Gets the current settings of the search algorithm.

Specified by:

getOptions in interface OptionHandler

Overrides:

getOptions in class SearchAlgorithm

Returns:

an array of strings suitable for passing to setOptions

getRevision

public String getRevision()

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Overrides:

getRevision in class SearchAlgorithm

Returns:

the revision
