 Valid options are: <p/>
 
 <pre> -Q
  Use resampling instead of reweighting for boosting.</pre>
 
 <pre> -P &lt;percent&gt;
  Percentage of weight mass to base training on.
  (default 100, reduce to around 90 speed up)</pre>
 
 <pre> -F &lt;num&gt;
  Number of folds for internal cross-validation.
  (default 0 -- no cross-validation)</pre>
 
 <pre> -R &lt;num&gt;
  Number of runs for internal cross-validation.
  (default 1)</pre>
 
 <pre> -L &lt;num&gt;
  Threshold on the improvement of the likelihood.
  (default -Double.MAX_VALUE)</pre>
 
 <pre> -H &lt;num&gt;
  Shrinkage parameter.

 <pre> -S &lt;num&gt;
  Random number seed.
  (default 1)</pre>
 
 <pre> -I &lt;num&gt;
  Number of iterations.
  (default 10)</pre>
 
 <pre> -D
  If set, classifier is run in debug mode and

 <pre> -W
  Full name of base classifier.
