public java.lang.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 java.lang.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 classSearchAlgorithm
- Parameters:
bayesNet
-instances
- the instances to work with- Throws:
java.lang.Exception
- if something goes wrong
-
getRevision
public java.lang.String getRevision()
Returns the revision string.- Specified by:
getRevision
in interfaceRevisionHandler
- Overrides:
getRevision
in classSearchAlgorithm
- Returns:
- the revision
