Method Detail

getHypothesisModel

public MooreMachine<?,I,Integer,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().

Returns:

the current hypothesis model.

stateProperty

protected O stateProperty(ObservationTable<I,O> table,
                          Row<I> stateRow)

Description copied from class: AbstractAutomatonLStar

Derives a state property from the corresponding row.

Specified by:

stateProperty in class AbstractAutomatonLStar<MooreMachine<?,I,?,O>,I,O,Integer,Integer,O,Void,CompactMoore<I,O>>

Parameters:

table - the current observation table

stateRow - the row for which the state is created

Returns:

the state property of the corresponding state

transitionProperty

protected Void transitionProperty(ObservationTable<I,O> table,
                                  Row<I> stateRow,
                                  int inputIdx)

Description copied from class: AbstractAutomatonLStar

Derives a transition property from the corresponding transition.

N.B.: Not the transition row is passed to this method, but the row for the outgoing state. The transition row can be retrieved using Row.getSuccessor(int).

Specified by:

transitionProperty in class AbstractAutomatonLStar<MooreMachine<?,I,?,O>,I,O,Integer,Integer,O,Void,CompactMoore<I,O>>

stateRow - the row for the source state

inputIdx - the index of the input symbol to consider

Returns:

the transition property of the corresponding transition

hypothesisOutput

protected SuffixOutput<I,O> hypothesisOutput()

Specified by:

hypothesisOutput in class AbstractLStar<MooreMachine<?,I,?,O>,I,O>
