Class NaiveBayes

  • All Implemented Interfaces:
    java.io.Serializable, OptionHandler, RevisionHandler

    public class NaiveBayes
    extends SearchAlgorithm
    The NaiveBayes class generates a fixed Bayes network structure with arrows from the class variable to each of the attribute variables.

                            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 class SearchAlgorithm
        Parameters:
        bayesNet -
        instances - the instances to work with
        Throws:
        java.lang.Exception - if something goes wrong
