Class PrepareForYale

java.lang.Object
  edu.udo.cs.miningmart.operator.ExecutableOperator
      edu.udo.cs.miningmart.operator.PrepareForYale

public class PrepareForYale
extends ExecutableOperator

This operator creates a YALE experiment file (XML) to ease the combination of MiningMart preprocessing and YALE learning. The YALE experiment created by this operator will contain a single YALE operator, an instance of DatabaseExampleSource, which reads the data for subsequent YALE operations from the Columnset specified by the InputConcept of this operator. If the InputConcept is connected to more than one Columnset, the YALE experiment chain will include an ExampleSetIterator which runs the YALE experiment for each input, ie here for the data of each Columnset.
