Category division is specified through the Coding Matrix. There are many forms of coding matrix, the common ones are binary code and ternary code. The former specifies each class as a positive class and an inverse class respectively, while the latter can specify "disabled class" in addition to the positive and inverse classes. FIG. 3.5 shows a schematic diagram. In FIG. 3.5 (a), classifier f2 takes samples of Cl and C3 as positive examples and samples of C2 and C4 as counterexamples. In FIG. 3.5 (B), classifier f4 takes the samples of C1 and C4 as positive examples and the samples of C3 as counterexamples. In the decoding stage, the prediction results of each classifier are combined to form the code of the test example. The code is compared with the corresponding codes of various types, and the category corresponding to the code with the smallest distance is taken as the prediction result. For example, in Figure 3.5 (a), if based on the European distance, the prediction result will be C3.终有一天，古老的国术会在新世纪绽放出最耀眼的光芒。　　如此纷繁复杂的素材，经过首席执行导演凯文·麦克唐纳（Kevin Macdonald）的构想与处理之后，究竟会整合出怎样的趣味来呢？10一名女子与自己因为遭到跟踪恐吓而雇佣的私人侦探发生关系，却没有意识到英俊的侦探远没有她所想的那样简单。詹姆斯从未想过一只流浪的橘猫可以拯救自己的人生。戒毒成功后的他与猫咪鲍勃过着贫苦却温馨的日子,一人一猫的卖唱风景总是能在街头成为焦点,为他们带来更多收入。眼看着生活开始有了起色,不料鲍勃却突然受伤,詹姆斯也面临着被迫和鲍勃分离的危机……　　张在法经西方文化与价值观熏陶，十分书生意气，刚携妻子（陈少霞）来到上海，便展开一系列动作，不知中国与西方国家国情有别，难有健全的法律体系及社会秩序：警察署长倪坤（顾宝明）和大毒枭戴济民（刘松仁）是拜把兄弟，两人一起控制着包括贩卖鸦片在内的上海所有的非法交易，见数次向张行贿无果，他们发毒誓要让张生不如死。
