getHypothesisModel
public MealyMachine<?,I,?,O> getHypothesisModel()
Description copied from interface:LearningAlgorithm
Returns the current hypothesis model.N.B.: By the contract of this interface, the model returned by this method may not be modified (i.e., M generally should refer to an immutable interface), and its validity is retained only until the next invocation of
LearningAlgorithm.refineHypothesis(DefaultQuery)
. If older hypotheses have to be maintained, a copy of the returned model must be made.Please note that it should be illegal to invoke this method before an initial invocation of
LearningAlgorithm.startLearning()
.- Specified by:
getHypothesisModel
in interfaceLearningAlgorithm<MealyMachine<?,I,?,O>,I,Word<O>>
- Returns:
- the current hypothesis model.
-
startLearning
public void startLearning()
Description copied from interface:LearningAlgorithm
Starts the model inference process, creating an initial hypothesis in the provided model object. Please note that it should be illegal to invoke this method twice.- Specified by:
startLearning
in interfaceLearningAlgorithm<M,I,D>
-
refineHypothesis
public boolean refineHypothesis(DefaultQuery<I,D> counterexample)
Description copied from interface:LearningAlgorithm
Triggers a refinement of the model by providing a counterexample. A counterexample is a query which exposes different behavior of the real SUL compared to the hypothesis. Please note that invoking this method before an initial invocation ofLearningAlgorithm.startLearning()
should be illegal.- Specified by:
refineHypothesis
in interfaceLearningAlgorithm<M,I,D>
- Parameters:
counterexample
- the query which exposes diverging behavior, as posed to the real SUL (i.e. with the SULs output).- Returns:
true
if the counterexample triggered a refinement of the hypothesis,false
otherwise (i.e., it was no counterexample).
-
getInputAlphabet
public Alphabet<I> getInputAlphabet()
- Specified by:
getInputAlphabet
in interfaceInputAlphabetHolder<M>
-
suspend
public OptimalLStarState<I,D> suspend()
Description copied from interface:Resumable
Expose the state object.
-
resume
public void resume(OptimalLStarState<I,D> state)
Description copied from interface:Resumable
Resume the datastructure from a previously suspended point in time.
