ParticleClassifier::~ParticleClassifier ( void  )
virtual

Default Destructor

Definition at line 50 of file ParticleClassifier.cpp.

Member Function Documentation

bool ParticleClassifier::clear ( )
virtual

This clears the ParticleClassifier classifier.

Returns
returns true if the ParticleClassifier model was successfully cleared, false otherwise.

Reimplemented from Classifier.

Definition at line 184 of file ParticleClassifier.cpp.

bool ParticleClassifier::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 ParticleClassifier instance) into this instance

Parameters
classifiera pointer to the Classifier Base Class, this should be pointing to another ParticleClassifier instance
Returns
returns true if the clone was successfull, false otherwise

Reimplemented from Classifier.

Definition at line 71 of file ParticleClassifier.cpp.

std::string ParticleClassifier::getId ( )
static

Gets a string that represents the ParticleClassifier class.

Returns
returns a string containing the ID of this class

Definition at line 28 of file ParticleClassifier.cpp.

bool ParticleClassifier::load ( std::fstream &  file)
virtual

This loads a trained ParticleClassifier model from a file. This overrides the load function in the Classifier base class.

Parameters
filea reference to the file the ParticleClassifier model will be loaded from
Returns
returns true if the model was loaded successfully, false otherwise

Reimplemented from MLBase.

Definition at line 213 of file ParticleClassifier.cpp.

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

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

Parameters
rhsanother instance of a ParticleClassifier
Returns
returns a pointer to this instance of the ParticleClassifier

Definition at line 54 of file ParticleClassifier.cpp.

bool ParticleClassifier::predict_ ( VectorFloat inputVector)
virtual

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

Parameters
inputVectorthe input vector to classify
Returns
returns true if the prediction was performed, false otherwise

Reimplemented from MLBase.

Definition at line 120 of file ParticleClassifier.cpp.

bool ParticleClassifier::reset ( )
virtual

This resets the ParticleClassifier classifier.

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

Reimplemented from Classifier.

Definition at line 193 of file ParticleClassifier.cpp.

bool ParticleClassifier::save ( std::fstream &  file) const
virtual

This saves the trained ParticleClassifier model to a file. This overrides the save function in the Classifier base class.

Parameters
filea reference to the file the ParticleClassifier model will be saved to
Returns
returns true if the model was saved successfully, false otherwise

Reimplemented from MLBase.

Definition at line 202 of file ParticleClassifier.cpp.

bool ParticleClassifier::train_ ( TimeSeriesClassificationData trainingData)
virtual

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

Parameters
trainingDataa reference to the training data
Returns
returns true if the DTW model was trained, false otherwise

Reimplemented from MLBase.
