Method Detail

learn

void learn(Dataset dataset)

It starts the training process exploiting the provided dataset

Parameters:

dataset - the training data

setLabels

void setLabels(List<Label> labels)

Sets the labels representing the concept to be learned.

Parameters:

labels - the labels representing the concept to be learned

getLabels

List<Label> getLabels()

Returns the labels representing the concept to be learned.

Returns:

the labels representing the concept to be learned

duplicate

LearningAlgorithm duplicate()

Creates a new instance of the LearningAlgorithm initialized with the same parameters of the learningAlgorithm to be duplicated. A shallow copy of the learning parameters is performed, while the state parameters are initialized to their default value. The labels are not initialized neither copied

reset

void reset()

Resets all the learning process, returning to the default state. All the learned process is forgotten

getPredictionFunction

PredictionFunction getPredictionFunction()

Returns the predictionFunction learned during the training process

Returns:

the predictionFunction learned during the training process

setPredictionFunction

void setPredictionFunction(PredictionFunction predictionFunction)

Sets the predictionFunction learned during the training process. It can be used to change the default prediction function, or to set an already trained one.
