public class QuadraticParameterOptimizationOperator
extends GridSearchParameterOptimizationOperator

This operator finds the optimal values for a set of parameters using a quadratic interaction model. The parameter parameters is a list of key value pairs where the keys are of the form OperatorName.parameter_name and the value is a comma separated list of values (as for the GridParameterOptimization operator).
The operator returns an optimal ParameterSet which can as well be written to a file with a ParameterSetLoader. This parameter set can be read in another process using an ParameterSetLoader.
The file format of the parameter set file is straightforward and can also easily be generated by external applications. Each line is of the form

operator_name.parameter_name = value.

Method Detail

getCurrentBestPerformance

public double getCurrentBestPerformance()

Overrides:

getCurrentBestPerformance in class GridSearchParameterOptimizationOperator

doWork

public void doWork()
            throws OperatorException

Description copied from class: Operator

Performs the actual work of the operator and must be implemented by subclasses. Replaces the old method apply().

Overrides:

doWork in class GridSearchParameterOptimizationOperator

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class ParameterIteratingOperatorChain
