public class FilteredSubsetEval
extends ASEvaluation
implements Serializable, SubsetEvaluator, OptionHandler
Class for running an arbitrary subset 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.CfsSubsetEval -L"
-F <filter specification> Full class name of filter to use, followed by filter options. eg: "weka.filters.supervised.instance.SpreadSubsample -M 1"
