Second, it is facing the problem of expansion in different places brought about by the choice of stores and different policies for running schools in different places. Third, the investment required for the construction and management of its stores is relatively heavy. Fourth, there is a shortage of outstanding management talents and it is difficult to duplicate store management talents.二零一零年，国家航天局挑选了一个香港科研团队作合作伙伴，于杰教授就是团队的掌舵人，他将会为登月任务研发「相机指向系统」。　　伟之母亲江霞﹝叶德娴﹞、父亲戚干﹝刘江﹞和女友王嘉琦﹝陈敏儿﹞不明伟的苦衷，误以为他自甘堕落，为此伤心不已。伟一面忍受家人的压力，一面埋首搜集罪证，几经辛苦，终成功将帆绳之于法。Weightlifting我别无选择。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.
