说明：  adboost算法的一个例子。在Kearns和Valiant在1989年大作中指出了这种算法的可行性。而后，Freund在 1990年以及他和Schapire在 1994-1996年提出了boosting整个算法思路，似乎这种算法走到 了实际应用的开端。然而直到AdaBoost被viola在其人脸识别系统中运用(2001Viola和 Jones)，这种方法才彻底开始暴火.
(An example adboost algorithm. Kearns and Valiant pointed at the feasibility of this method in 1989 masterpiece. Then, Freund and Schapire he made in 1990 and in 1994-1996 the idea of ​ ​ boosting the entire algorithm, this algorithm seems to come to the beginning of the practical application. However, until the use of AdaBoost is viola (2001Viola and Jones) in its face recognition systems, this approach was completely start a fire storm.)
