For more information, see<p> R. Kohavi (1995). <i>Wrappers for Performance Enhancement and Oblivious Decision Graphs</i>. PhD Thesis. Department of Computer Science, Stanford University. <p> Valid options are:<p> -D <br> Turn on debugging output.<p> -W classname <br> Specify the full class name of classifier to perform cross-validation selection on.<p> -X num <br> Number of folds used for cross validation (default 10). <p> -S seed <br> Random number seed (default 1).<p> -P "N 1 5 10" <br> Sets an optimisation parameter for the classifier with name -N, lower bound 1, upper bound 5, and 10 optimisation steps. The upper bound may be the character 'A' or 'I' to substitute the number of attributes or instances in the training data, respectively. This parameter may be supplied more than once to optimise over several classifier options simultaneously. <p> Options after -- are passed to the designated sub-classifier.
