public class RandomSubset extends SimpleStreamFilter
-N <double> The number of attributes to randomly select. If < 1 then percentage, >= 1 absolute number. (default: 0.5)
-V Invert selection - i.e. randomly remove rather than select.
-S <int> The seed value. (default: 1)
-output-debug-info If set, filter is run in debug mode and may output additional info to the console
-do-not-check-capabilities If set, filter capabilities are not checked before filter is built (use with caution).
