    • 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 something goes wrong
    • getRevision

      public String getRevision()
      Returns the revision string.
      Specified by:
      getRevision in interface RevisionHandler
      Overrides:
      getRevision in class SearchAlgorithm
      Returns:
      the revision
