Constructor & Destructor Documentation

ANBC::ANBC	(	bool	useScaling = `false`,
		bool	useNullRejection = `false`,
		double	nullRejectionCoeff = `10.0`
	)

Default Constructor

Parameters

useScaling	sets if the training and prediction data should be scaled to a specific range. Default value is useScaling = false
useNullRejection	sets if null rejection will be used for the realtime prediction. If useNullRejection is set to true then the predictedClassLabel will be set to 0 (which is the default null label) if the distance between the inputVector and the top K datum is greater than the null rejection threshold for the top predicted class. The null rejection threshold is computed for each class during the training phase. Default value is useNullRejection = false
nullRejectionCoeff	sets the null rejection coefficient, this is a multipler controlling the null rejection threshold for each class. This will only be used if the useNullRejection parameter is set to true. Default value is nullRejectionCoeff = 10.0

ANBC::ANBC ( const ANBC & rhs )

Defines the copy constructor.

Parameters

const ANBC &rhs: the instance from which all the data will be copied into this instance

Definition at line 44 of file ANBC.cpp.

ANBC::~ANBC ( void )

virtual

Default Destructor

Definition at line 55 of file ANBC.cpp.

Member Function Documentation

bool ANBC::clear ( )

virtual

This overrides the clear function in the Classifier base class. It will completely clear the ML module, removing any trained model and setting all the base variables to their default values.

Returns: returns true if the module was cleared succesfully, false otherwise

Reimplemented from Classifier.

Definition at line 288 of file ANBC.cpp.

bool ANBC::clearWeights ( )

inline

Clears any previously set weights.

Returns: returns true if the weights were correctly cleared, false otherwise

Definition at line 189 of file ANBC.h.

bool ANBC::deepCopyFrom ( const Classifier * classifier )

virtual

This is required for the Gesture Recognition Pipeline for when the pipeline.setClassifier(...) method is called. It clones the data from the Base Class Classifier pointer (which should be pointing to an ANBC instance) into this instance

Parameters

classifier a pointer to the Classifier Base Class, this should be pointing to another ANBC instance

Returns: returns true if the clone was successfull, false otherwise

Reimplemented from Classifier.

Definition at line 72 of file ANBC.cpp.

Vector< ANBC_Model > ANBC::getModels ( )

inline

Returns the ANBC models for each of the classes.

Returns: returns a vector of the ANBC models for each of the classes

Definition at line 163 of file ANBC.h.

VectorFloat ANBC::getNullRejectionThresholds ( ) const

Gets a vector containing the null rejection thresholds for each class, this will be an N-dimensional vector, where N is the number of classes in the model.

Returns: returns a vector containing the null rejection thresholds for each class, an empty vector will be returned if the model has not been trained

Definition at line 511 of file ANBC.cpp.

bool ANBC::loadLegacyModelFromFile ( std::fstream & file )

protected

Read the ranges if needed

Definition at line 536 of file ANBC.cpp.

bool ANBC::loadModelFromFile ( std::fstream & file )

virtual

This loads a trained ANBC model from a file. This overrides the loadModelFromFile function in the Classifier base class.

Parameters

file	a reference to the file the ANBC model will be loaded from

Returns: returns true if the model was loaded successfully, false otherwise

Reimplemented from MLBase.

Definition at line 349 of file ANBC.cpp.

ANBC & ANBC::operator= ( const ANBC & rhs )

Defines how the data from the rhs ANBC should be copied to this ANBC

Parameters

rhs	another instance of a ANBC

Returns: returns a pointer to this instance of the ANBC

Definition at line 59 of file ANBC.cpp.

bool ANBC::predict_ ( VectorFloat & inputVector )

virtual

This predicts the class of the inputVector. This overrides the predict function in the Classifier base class.

Parameters

inputVector the input vector to classify

Returns: returns true if the prediction was performed, false otherwise

Reimplemented from MLBase.

Definition at line 199 of file ANBC.cpp.

bool ANBC::recomputeNullRejectionThresholds ( )

virtual

This recomputes the null rejection thresholds for each of the classes in the ANBC model. This will be called automatically if the setGamma(double gamma) function is called. The ANBC model needs to be trained first before this function can be called.

Returns: returns true if the null rejection thresholds were updated successfully, false otherwise

Reimplemented from Classifier.

Definition at line 270 of file ANBC.cpp.

bool ANBC::reset ( )

virtual

This resets the ANBC classifier.

Returns: returns true if the ANBC model was successfully reset, false otherwise.

Reimplemented from Classifier.

Definition at line 284 of file ANBC.cpp.

bool ANBC::saveModelToFile ( std::fstream & file ) const

virtual

This saves the trained ANBC model to a file. This overrides the saveModelToFile function in the Classifier base class.

Parameters

file	a reference to the file the ANBC model will be saved to

Returns: returns true if the model was saved successfully, false otherwise

Reimplemented from MLBase.

Definition at line 300 of file ANBC.cpp.

bool ANBC::setNullRejectionCoeff ( double nullRejectionCoeff )

Sets the nullRejectionCoeff parameter. The nullRejectionCoeff parameter is a multipler controlling the null rejection threshold for each class. This function will also recompute the null rejection thresholds.

Returns: returns true if the gamma parameter was updated successfully, false otherwise

Definition at line 516 of file ANBC.cpp.

bool ANBC::setWeights ( const ClassificationData & weightsData )

Sets the weights for the training and prediction. The dimensionality of the weights should match that of the training data used to train the ANBC models. The weights should be encapsualted into a LabelledClassificationData container, with one training sample for each class.

Returns: returns true if the weights were correctly set, false otherwise

Definition at line 526 of file ANBC.cpp.

bool ANBC::train_ ( ClassificationData & trainingData )

virtual

This trains the ANBC model, using the labelled classification data. This overrides the train function in the Classifier base class.

Parameters

trainingData a reference to the training data

Returns: returns true if the ANBC model was trained, false otherwise

Reimplemented from MLBase.

Definition at line 90 of file ANBC.cpp.
