Comprehensive experiments have demonstrated that this technique is consistently more accurate than the base classifier,  Bagging and Random Forests. Decorate also obtains higher accuracy than Boosting on small training sets, and achieves comparable performance on larger training sets.  For more details see: <p> Prem Melville and Raymond J. Mooney. <i>Constructing diverse classifier ensembles using artificial training examples.</i> Proceedings of the Seventeeth International Joint Conference on Artificial Intelligence 2003.<p> Prem Melville and Raymond J. Mooney. <i>Creating diversity in ensembles using artificial data.</i> Submitted.<BR><BR> Valid options are:<p> -D <br> Turn on debugging output.<p> -W classname <br> Specify the full class name of a weak classifier as the basis for  Decorate (default weka.classifiers.trees.J48()).<p> -I num <br> Specify the desired size of the committee (default 15). <p> -M iterations <br> Set the maximum number of Decorate iterations (default 50). <p> -S seed <br> Seed for random number generator.
