Constructor Detail

AbstractSemanticMemoryLite

public AbstractSemanticMemoryLite(SemanticIdentifierMap semanticIdentifierMap,
                                  PatternRecognizerLite recognizer)

Creates a new instance of AbstractSemanticMemoryLite.

Parameters:

semanticIdentifierMap - The SemanticIdentifierMap to use for mapping SemanticLabels to SemanticIdentifiers.

recognizer - The PatternRecognizerLite used by this.

Method Detail

buildOutputMapping

protected void buildOutputMapping()

Builds the mapping of output identifiers to their labels.

initializeState

public CognitiveModuleState initializeState(CognitiveModelState modelState)

This method initializes the state object for the CognitiveModule by calling the initialState function on the underlying pattern recognizer.

Specified by:

initializeState in interface CognitiveModule

Parameters:

modelState - The CognitiveModelState to initalize

Returns:

The initial state of the CognitiveModule

update

public CognitiveModuleState update(CognitiveModelState modelState,
                                   CognitiveModuleState previousModuleState)

Updates the state of the cognitive model by modifying the given CognitiveModelState object.

Specified by:

update in interface CognitiveModule

Parameters:

modelState - The CognitiveModelState to update.

previousModuleState - The previous CognitiveModuleState returned by this module.

Returns:

The updated CognitiveModuleState for this module.

findInputIndexForIdentifier

public abstract int findInputIndexForIdentifier(SemanticIdentifier semanticIdentifier)

Finds the input vector index for a given identifier. If the identifier is not in the index, -1 is returned.

Parameters:

semanticIdentifier - The identifier to find the input index of.

Returns:

The input vector index for the given identifier, if it is part of the input vector. -1 otherwise.

getNetwork

public SemanticNetwork getNetwork()

Gets the semantic network underlying the semantic memory.

Specified by:

getNetwork in interface SemanticMemory

Returns:

The SemanticNetwork under the memory.

getSemanticIdentifierMap

public SemanticIdentifierMap getSemanticIdentifierMap()

Gets the semantic identifier map being used.

Returns:

The semantic identifier map being used.

getRecognizer

public PatternRecognizerLite getRecognizer()

Gets the pattern recognizer lite for the semantic memory lite.

Returns:

The pattern recognizer for the semantic memory lite.

getOutputIdentifiers

protected java.util.ArrayList<SemanticIdentifier> getOutputIdentifiers()

Gets the ordered list of output identifiers.

Returns:

The ordered list of output identifiers.
