说明：  当弱分类器算法使用简单的分类方时,boosting的效果明显地统一地比bagging要好.当弱分类器算法使用C4.5时,boosting比bagging较好,但是没有前者的比较来得明显.
(When the weak classifier algorithm using simple classification method, boosting the effect clearly uniformly better than bagging. When the weak classifier algorithm C4.5 when used, boosting ratio bagging better, but without the former Comparative more obvious.)
