Class PclBeliefSetQuadraticErrorMinimizationMachineShop

java.lang.Object

net.sf.tweety.logics.pcl.analysis.PclBeliefSetQuadraticErrorMinimizationMachineShop

All Implemented Interfaces:

BeliefBaseMachineShop

public class PclBeliefSetQuadraticErrorMinimizationMachineShop
extends java.lang.Object
implements BeliefBaseMachineShop

This class is capable of restoring consistency of a possible inconsistent probabilistic conditional belief set. Restoring consistency is performed by minimizing the quadratic distance to the original belief set using some culpability measure, see [Diss, Thimm] for details.

Constructor Detail

PclBeliefSetQuadraticErrorMinimizationMachineShop

public PclBeliefSetQuadraticErrorMinimizationMachineShop(CulpabilityMeasure<ProbabilisticConditional,PclBeliefSet> culpabilityMeasure)

Creates a new machine shop based on the given culpability measure.

Parameters:

culpabilityMeasure - a culpability measure.

Method Detail

repair

public BeliefBase repair(BeliefBase beliefBase)

Description copied from interface: BeliefBaseMachineShop

Repairs the given belief base, i.e. restores consistency.

Specified by:

repair in interface BeliefBaseMachineShop

Parameters:

beliefBase - a possibly inconsistent belief base.

Returns:

a consistent belief base that is as close as possible to the given belief base. NOTE: if the given belief base is consistent this method is expected to return it unmodified.
