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.公元1582年(万历十年)夏天的北京，怪事与奇案叠起。先是大明内库储银不翼而飞，从各地府县运来的大宗税银突然不知去向，国家铸银局的熔银大炉也因无银可铸而被迫停炉；接着便是被送入诏狱的两个江洋大盗神秘越狱，城外一个以做棺材为业的村子在一夜之间被杀戮一空；更可怕的是，一股来路不明的号称“江洋八子”的犯罪集团突然显身大街小巷和王公府邸……可是这是一个不争的事实，确确实实的事实，出自汉王刘邦之口，权威性自然不容质疑。　　巡山队员在遍布危险的茫茫大戈壁上奋力追踪，终于，盗猎者出现在冰河对岸，队员们不顾一切地冲入湍急的冰河之中。一场生死搏斗之后，只捕获了一些盗猎分子， 狡猾的盗猎头子再次漏网……Template Method Mode:等田遥那边事查清了，你自己跟他说。
