Constructor Detail

AbstractAxiomLearningAlgorithm

public AbstractAxiomLearningAlgorithm()

Method Detail

start

public void start()

Description copied from interface: LearningAlgorithm

Starts the algorithm. It runs until paused, stopped, or a termination criterion has been reached.

Specified by:

start in interface LearningAlgorithm

init

public void init()
          throws ComponentInitException

Description copied from interface: Component

Method to be called after the component has been configured. Implementation of components can overwrite this method to perform setup and initialisation tasks for this component.

Specified by:

init in interface Component

Throws:

ComponentInitException - This exception is thrown if any exceptions occur within the initialisation process of this component. As component developer, you are encouraged to rethrow occuring exception as ComponentInitException and giving an error message as well as the actualy exception by using the constructor ComponentInitException.ComponentInitException(String, Throwable).

getCurrentlyBestAxioms

public List<Axiom> getCurrentlyBestAxioms()

Specified by:

getCurrentlyBestAxioms in interface AxiomLearningAlgorithm

Returns:

The best axioms found by the learning algorithm so far.

getCurrentlyBestAxioms

public List<Axiom> getCurrentlyBestAxioms(int nrOfAxioms)

Specified by:

getCurrentlyBestAxioms in interface AxiomLearningAlgorithm

Parameters:

nrOfAxioms - Limit for the number or returned axioms.

Returns:

The best axioms found by the learning algorithm so far.

getCurrentlyBestAxioms

public List<Axiom> getCurrentlyBestAxioms(int nrOfAxioms,
                                          double accuracyThreshold)

getCurrentlyBestEvaluatedAxioms

public List<EvaluatedAxiom> getCurrentlyBestEvaluatedAxioms()

Specified by:

getCurrentlyBestEvaluatedAxioms in interface AxiomLearningAlgorithm

Returns:

The best evaluated axioms found by the learning algorithm so far.

getCurrentlyBestEvaluatedAxioms

public List<EvaluatedAxiom> getCurrentlyBestEvaluatedAxioms(int nrOfAxioms)

Specified by:

getCurrentlyBestEvaluatedAxioms in interface AxiomLearningAlgorithm

Parameters:

nrOfAxioms - Limit for the number or returned evaluated axioms.

Returns:

The best evaluated axioms found by the learning algorithm so far.

getCurrentlyBestEvaluatedAxioms

public List<EvaluatedAxiom> getCurrentlyBestEvaluatedAxioms(int nrOfAxioms,
                                                            double accuracyThreshold)

getConfigurator

public Configurator getConfigurator()

Description copied from class: AbstractComponent

For each component, a configurator class is generated in package org.dllearner.core.configurators using the script { org.dllearner.scripts.ConfigJavaGenerator}. The configurator provides set and get methods for the configuration options of a component.

Specified by:

getConfigurator in class AbstractComponent

Returns:

An object allowing to configure this component.
