train

public void train(DataSet trainingData)
           throws java.lang.Exception

Overrides:

train in class Classifier

classify

public Feature classify(Example example)

Overrides:

classify in class Classifier

getAccuracy

public double getAccuracy(DataSet testData)

getAccuracy() : This method is overidden to increase the speed by calling c50classify on a case file created from the whole dataset rather than creating a file per example. cuts down on process creation (only 1 process call rather than n calls).

Overrides:

getAccuracy in class Classifier

getOutputClass

public java.lang.String getOutputClass()

getOutputClass

public java.lang.String[] getOutputClass(int num)

getCommandString

public java.lang.String getCommandString()

printClassifier

public java.lang.String printClassifier()

Overrides:

printClassifier in class Classifier

cloneClassifier

public Classifier cloneClassifier()

Overrides:

cloneClassifier in class Classifier

setParameter

public void setParameter(int i,
                         java.lang.Object par)

Overrides:

setParameter in class Classifier
