Method Detail

createDAGCache

public static <I,O> MealyCacheOracle<I,O> createDAGCache(Alphabet<I> alphabet,
                                                         MembershipOracle<I,Word<O>> mqOracle)

Creates a cache oracle for a Mealy machine learning setup, using a DAG for internal cache organization.

Parameters:

alphabet - the input alphabet

mqOracle - the membership oracle

Returns:

a Mealy learning cache with a DAG-based implementation

createDAGCache

public static <I,O> MealyCacheOracle<I,O> createDAGCache(Alphabet<I> alphabet,
                                                         Mapping<? super O,? extends O> errorSyms,
                                                         MembershipOracle<I,Word<O>> mqOracle)

Creates a cache oracle for a Mealy machine learning setup, using a DAG for internal cache organization.

Parameters:

alphabet - the input alphabet

errorSyms - a mapping for the prefix-closure filter

mqOracle - the membership oracle

Returns:

a Mealy learning cache with a DAG-based implementation

createTreeCache

public static <I,O> MealyCacheOracle<I,O> createTreeCache(Alphabet<I> alphabet,
                                                          MembershipOracle<I,Word<O>> mqOracle)

Creates a cache oracle for a Mealy machine learning setup, using a tree for internal cache organization.

Parameters:

alphabet - the input alphabet

mqOracle - the membership oracle

Returns:

a Mealy learning cache with a tree-based implementation

createTreeCache

public static <I,O> MealyCacheOracle<I,O> createTreeCache(Alphabet<I> alphabet,
                                                          Mapping<? super O,? extends O> errorSyms,
                                                          MembershipOracle<I,Word<O>> mqOracle)

Creates a cache oracle for a Mealy machine learning setup, using a tree for internal cache organization.

Parameters:

alphabet - the input alphabet

errorSyms - a mapping for the prefix-closure filter

mqOracle - the membership oracle

Returns:

a Mealy learning cache with a tree-based implementation

createCache

public static <I,O> MealyCacheOracle<I,O> createCache(Alphabet<I> alphabet,
                                                      MembershipOracle<I,Word<O>> mqOracle)

Creates a cache oracle for a Mealy machine learning setup.

Note that this method does not specify the implementation to use for the cache. Currently, a DAG (IncrementalMealyDAGBuilder) is used; however, this may change in the future.

Parameters:

alphabet - the input alphabet

mqOracle - the membership oracle

Returns:

a Mealy learning cache with a default implementation
