public class FeatureStreamWithFSSExperiment
extends FeatureStreamImplementationExperiment

Represents an experiment that processes a feature stream with online feature subset selection using a MultiCTBNC. It iteratively updates the model with new features and validates the final model's performance.

Initializes a FeatureStreamWithFSSExperiment with the provided configuration parameters.

Parameters:

pathFeatureStream - path to the feature stream

nameTimeVariable - name of the time variable

nameClassVariables - list of names of class variables

initialDatasetReader - DatasetReader for the initial dataset

testDatasetReader - DatasetReader for the test dataset

ctbnPLA - parameter learning algorithm for the CIM nodes

maxSeparatingSizeFSS - maximum separating size for the feature subset selection

experimentNumber - number identifying the experiment

numFeatures - number of features in the dataset (used to identify results files)

areModelsValidated - boolean indicating whether the models should be validated

sigTimeTransitionHyp - significance level for time transition hypothesis

sigStateToStateTransitionHyp - significance level for state-to-state transition hypothesis

Throws:

UnreadDatasetException - if there is an issue reading the dataset

IOException - if there is an I/O error
