Name

adams.flow.transformer.WekaClassSelector

Synopsis

Sets the class index. Can either honour an already existing one or override it. Also, one can apply the index on a subset of attributes defined by a regular expression applied to the attribute names (one can set the class index to the last attribute that starts with 'att_').

Additional information

Flow input/output:
- input: weka.core.Instance, weka.core.Instances, adams.data.instance.Instance
- output: weka.core.Instance, weka.core.Instances, adams.data.instance.Instance
