Synopsis

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.

Options

The table below describes the options available for NaiveBayesUpdateable.

Option	Description
debug	If set to true, classifier may output additional info to the console.
displayModelInOldFormat	Use old format for model output. The old format is better when there are many class values. The new format is better when there are fewer classes and many attributes.
useKernelEstimator	Use a kernel estimator for numeric attributes rather than a normal distribution.
useSupervisedDiscretization	Use supervised discretization to convert numeric attributes to nominal ones.
