Method Detail

init

public void init(RandomGenerator random)

Does nothing.

Specified by:

init in interface TargetFunction

setTotalNumberOfExamples

public void setTotalNumberOfExamples(int number)

Description copied from interface: TargetFunction

Sets the maximal number of examples. This might be used by some target functions in order to create proper arguments.

Specified by:

setTotalNumberOfExamples in interface TargetFunction

getTotalNumberOfExamples

public int getTotalNumberOfExamples()

setTotalNumberOfAttributes

public void setTotalNumberOfAttributes(int number)

Description copied from interface: TargetFunction

Sets the maximal number of attributes. This might be used by some target functions in order to create proper arguments.

Specified by:

setTotalNumberOfAttributes in interface TargetFunction

getTotalNumberOfAttributes

public int getTotalNumberOfAttributes()

setLowerArgumentBound

public void setLowerArgumentBound(double lower)

Description copied from interface: TargetFunction

Sets the lower bound for the arguments.

Specified by:

setLowerArgumentBound in interface TargetFunction

setUpperArgumentBound

public void setUpperArgumentBound(double upper)

Description copied from interface: TargetFunction

Sets the upper bound for the arguments.

Specified by:

setUpperArgumentBound in interface TargetFunction

getLabel

public Attribute getLabel()

Description copied from interface: TargetFunction

Returns the label attribute.

Specified by:

getLabel in interface TargetFunction

createArguments

public double[] createArguments(int dimension,
                                RandomGenerator random)

Description copied from interface: TargetFunction

Creates and returns a number of arguments.

Specified by:

createArguments in interface TargetFunction

getGeneratedMetaData

public ExampleSetMetaData getGeneratedMetaData()

Description copied from interface: TargetFunction

This method returns the meta data of the generated data.

Specified by:

getGeneratedMetaData in interface TargetFunction
