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.讲述以毛泽东为代表的中国共产党第一代领导人，在国家民族危难之际，召开中国共产党第一次代表大会，建立中国共产党，并带领共产党不懈探索，走向成熟的伟大历程。故事以毛泽东为主的“一大代表”为视角，从1919年之后中国社会主要矛盾出发，以党的发展脉络为根基，展现了革命先辈们在党面临危急关头，在民族遭受危难时刻，通过艰苦卓绝的奋斗，开辟了一条前所未有的革命道路，最终取得了伟大胜利。这是每一个华夏人、炎黄子孙都应该懂得的。2716
