public class NaiveBayesUpdateable
extends NaiveBayes
implements UpdateableClassifier

Class for a Naive Bayes classifier using estimator classes. This is the updateable version of NaiveBayes.
This classifier will use a default precision of 0.1 for numeric attributes when buildClassifier is called with zero training instances.

For more information on Naive Bayes classifiers, see

George H. John, Pat Langley: Estimating Continuous Distributions in Bayesian Classifiers. In: Eleventh Conference on Uncertainty in Artificial Intelligence, San Mateo, 338-345, 1995.

Valid options are:

 -K
  Use kernel density estimator rather than normal
  distribution for numeric attributes

 -D
  Use supervised discretization to process numeric attributes
 

 -O
  Display model in old format (good when there are many classes)
