ClassificationData

public ClassificationData(List<CsvDataLoader.ClassificationData.Row> rows,
 List<String> featureOrder,
 List<String> classValues,
 Map<String,Integer> classIndexByLabel)

Creates an instance of a ClassificationData record class.

Parameters:

rows - the value for the rows record component

featureOrder - the value for the featureOrder record component

classValues - the value for the classValues record component

classIndexByLabel - the value for the classIndexByLabel record component

Method Details

classCount

public int classCount()

Number of distinct classes.

classIndex

public int classIndex(String label)

Resolves class label into a dense class index.
