java.lang.Objectweka.attributeSelection.ASEvaluation
weka.attributeSelection.FilteredAttributeEval
public class FilteredAttributeEval
Class for running an arbitrary attribute evaluator on data that has been passed through an arbitrary filter (note: filters that alter the order or number of attributes are not allowed). Like the evaluator, the structure of the filter is based exclusively on the training data.
Valid options are:-W <evaluator specification> Full name of base evaluator to use, followed by evaluator options. eg: "weka.attributeSelection.InfoGainAttributeEval -M"
-F <filter specification> Full class name of filter to use, followed by filter options. eg: "weka.filters.supervised.instance.SpreadSubsample -M 1"
