es.upm.fi.cig.multictbnc.data.reader.SingleCSVReader

All Implemented Interfaces:

DatasetReader

public class SingleCSVReader
extends AbstractCSVReader

Reads time series data contained in a single CSV. It divides the dataset into several sequences depending on the selected strategy.

Constructor Details

SingleCSVReader

public SingleCSVReader(String datasetFolder,
 int sizeSequence)
                throws FileNotFoundException,
UnreadDatasetException

Constructs a SingleCSVReader that extracts a CSV file from the specified folder.

Parameters:

datasetFolder - folder path where the CSV file is stored

sizeSequence - maximum size of the sequences

Throws:

FileNotFoundException - if the CSV file was not found

UnreadDatasetException - if a dataset could not be read from the specified folder

Method Details

extractFixedSequences

public void extractFixedSequences(Dataset dataset,
 List<String[]> dataCSV)

Extracts sequences that have the same maximum length and add them to the specified dataset. It is assumed that the names of the variables are in the first array of "dataCSV".

Parameters:

dataset - a Dataset where sequences are stored

dataCSV - list of String arrays with the data extracted from the CSV file. The first array in the list must contain the name of the variables

extractFixedSequencesSameCC

public void extractFixedSequencesSameCC(Dataset dataset,
 List<String[]> dataCSV)

Extracts sequences that have the same maximum length and add them to the specified dataset. Observations of a sequence must belong to the same class configuration. Therefore, sequences could contain less observation if a transition of a class variable occurs before reaching the maximum sequence size. It is assumed that the names of the variables are in the first array of "dataCSV".

Parameters:

dataset - a Dataset where sequences are stored

dataCSV - list of String arrays with the data extracted from the CSV file. The first array in the list must contain the name of the variables

readDataset

public Dataset readDataset()
                    throws UnreadDatasetException

Description copied from interface: DatasetReader

Returns a dataset.

Returns:

a Dataset

Throws:

UnreadDatasetException - if the provided dataset could not be read
