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.谁料凭空起波澜，连皇上都插手，不让张家轻易认他这个儿子，真是太好了。No.72 Fattah Amin　　Justin Kirk将饰演剧中亿万富翁兼天才Gideon Reeves，在带着孩子气的好奇心时，同时也有令人难以抗拒的魅力。在好友被谋杀后，决定要把原本的警察系统大大改变。在剧中他为警局开发了一个新应用 – APB，并提供各种高科技玩意给警员。1.
