java.lang.Object
  uk.ac.ed.inf.taweka.DataSetWriter
      uk.ac.ed.inf.taweka.mulan.MulanDataSetWriter

public class MulanDataSetWriter
extends DataSetWriter

This class generates a data set (instances, attributes, classes) in Mulan style (for multi-label machine learning). The main difference compared with the classic Weka ARFF, is that there are multiple classes and each is simply listed as a normal binary {0, 1} attribute. The class attributes must also be specified in a separate Mulan XML.
