Method Detail

setAlgorithm

public void setAlgorithm(Algorithm algorithm)

setAttributes

public DecisionTree setAttributes(java.lang.String[] attributeNames)

Saves the array of attribute names in an insertion ordered set. The ordering of attribute names is used when addExamples is called to determine which values correspond with which names.

setDecisions

public DecisionTree setDecisions(java.lang.String attributeName,
                                 java.lang.String[] decisions)

addExample

public DecisionTree addExample(java.lang.String[] attributeValues,
                               boolean classification)
                        throws UnknownDecisionException

Throws:

UnknownDecisionException

addExample

public DecisionTree addExample(java.util.Map<java.lang.String,java.lang.String> attributes,
                               boolean classification)
                        throws UnknownDecisionException

Throws:

UnknownDecisionException

apply

public boolean apply(java.util.Map<java.lang.String,java.lang.String> data)
              throws BadDecisionException

Throws:

BadDecisionException

compile
