| NBTreeNoSplit | | public NBTreeNoSplit()(Code) | | |
| buildClassifier | | final public void buildClassifier(Instances instances) throws Exception(Code) | | Build the no-split node
Parameters:
instances - an Instances value
exception:
Exception - if an error occurs |
| classProb | | public double classProb(int classIndex, Instance instance, int theSubset) throws Exception(Code) | | Return the probability for a class value
Parameters:
classIndex - the index of the class value
Parameters:
instance - the instance to generate a probability for
Parameters:
theSubset - the subset to consider a probability
exception:
Exception - if an error occurs |
| crossValidate | | public static double crossValidate(NaiveBayesUpdateable fullModel, Instances trainingSet, Random r) throws Exception(Code) | | Utility method for fast 5-fold cross validation of a naive bayes
model
Parameters:
fullModel - a NaiveBayesUpdateable value
Parameters:
trainingSet - an Instances value
Parameters:
r - a Random value a double value
exception:
Exception - if an error occurs |
| getDiscretizer | | public Discretize getDiscretizer()(Code) | | Return the discretizer used at this node
a Discretize value |
| getErrors | | public double getErrors()(Code) | | Return the errors made by the naive bayes model at this node
the number of errors made |
| getNaiveBayesModel | | public NaiveBayesUpdateable getNaiveBayesModel()(Code) | | Get the naive bayes model at this node
a NaiveBayesUpdateable value |
| leftSide | | final public String leftSide(Instances instances)(Code) | | Does nothing because no condition has to be satisfied.
|
| rightSide | | final public String rightSide(int index, Instances instances)(Code) | | Does nothing because no condition has to be satisfied.
|
| sourceExpression | | final public String sourceExpression(int index, Instances data)(Code) | | Returns a string containing java source code equivalent to the test
made at this node. The instance being tested is called "i".
Parameters:
index - index of the nominal value tested
Parameters:
data - the data containing instance structure info a value of type 'String' |
| toString | | public String toString()(Code) | | Return a textual description of the node
a String value |
| weights | | final public double[] weights(Instance instance)(Code) | | Always returns null because there is only one subset.
|
| whichSubset | | final public int whichSubset(Instance instance)(Code) | | Always returns 0 because only there is only one subset.
