  • Method Details

    • 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
