public class CheckAttributeSelection extends CheckScheme
java weka.attributeSelection.CheckAttributeSelection -W ASscheme_name
-- ASscheme_options
CheckAttributeSelection reports on the following:
weka.attributeSelection.AbstractAttributeSelectionTest
uses this class to test all the schemes. Any changes here, have to be
checked in that abstract test class, too.
Valid options are:
-D Turn on debugging output.
-S Silent mode - prints nothing to stdout.
-N <num> The number of instances in the datasets (default 20).
-nominal <num> The number of nominal attributes (default 2).
-nominal-values <num> The number of values for nominal attributes (default 1).
-numeric <num> The number of numeric attributes (default 1).
-string <num> The number of string attributes (default 1).
-date <num> The number of date attributes (default 1).
-relational <num> The number of relational attributes (default 1).
-num-instances-relational <num> The number of instances in relational/bag attributes (default 10).
-words <comma-separated-list> The words to use in string attributes.
-word-separators <chars> The word separators to use in string attributes.
-eval name [options] Full name and options of the evaluator analyzed. eg: weka.attributeSelection.CfsSubsetEval
-search name [options] Full name and options of the search method analyzed. eg: weka.attributeSelection.Ranker
-test <eval|search> The scheme to test, either the evaluator or the search method. (Default: eval)
Options specific to evaluator weka.attributeSelection.CfsSubsetEval:
-M Treat missing values as a seperate value.
-L Don't include locally predictive attributes.
Options specific to search method weka.attributeSelection.Ranker:
-P <start set> Specify a starting set of attributes. Eg. 1,3,5-7. Any starting attributes specified are ignored during the ranking.
-T <threshold> Specify a theshold by which attributes may be discarded from the ranking.
-N <num to select> Specify number of attributes to select
