Method Detail

getWeightingOperator

public PopulationOperator getWeightingOperator(java.lang.String parameter)

Specified by:

getWeightingOperator in class FeatureWeighting

createInitialPopulation

public Population createInitialPopulation(ExampleSet es)

Description copied from class: FeatureOperator

Create an initial population. The example set will be cloned before the method is invoked. This method is invoked after the pre- and postevaluation population operators were collected.

Specified by:

createInitialPopulation in class FeatureOperator
