java.lang.Objectweka.filters.Filter
weka.filters.unsupervised.instance.Randomize
This filter randomly shuffles the order of instances passed through it. The random number generator is reset with the seed value whenever setInputFormat() is called.
Valid filter-specific options are:
-S num
Specify the random number seed (default 42).
