Class for building and using a 0-R classifier. Predicts the mean (for a numeric class) or the mode (for a nominal class).
Valid options are:
-D If set, classifier is run in debug mode and may output additional info to the console

globalInfo
Returns a string describing classifier- 返回:
- a description suitable for displaying in the explorer/experimenter gui
-
getCapabilities
Returns default capabilities of the classifier.- 指定者:
getCapabilities
在接口中CapabilitiesHandler
- 覆盖:
getCapabilities
在类中Classifier
- 返回:
- the capabilities of this classifier

-
buildClassifier
Generates the classifier.- 指定者:
buildClassifier
在类中Classifier
- 参数:
instances
- set of instances serving as training data- 抛出:
Exception
- if the classifier has not been generated successfully
-
classifyInstance
Classifies a given instance.- 覆盖:
classifyInstance
在类中Classifier
- 参数:
instance
- the instance to be classified- 返回:
- index of the predicted class
-
distributionForInstance
Calculates the class membership probabilities for the given test instance.- 覆盖:
distributionForInstance
在类中Classifier
- 参数:
instance
- the instance to be classified- 返回:
- predicted class probability distribution
- 抛出:
Exception
- if class is numeric
-
toSource
Returns a string that describes the classifier as source. The classifier will be contained in a class with the given name (there may be auxiliary classes), and will contain a method with the signature:
where the arraypublic static double classify(Object[] i);
i
contains elements that are either Double, String, with missing values represented as null. The generated code is public domain and comes with no warranty. -
toString
Returns a description of the classifier. -
getRevision
Returns the revision string.- 指定者:
getRevision
在接口中RevisionHandler
- 覆盖:
getRevision
在类中Classifier
- 返回:
- the revision
-
main
Main method for testing this class.- 参数:
argv
- the options
