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.In addition, As Zhang Xiaobo said, On the front line at that time, Wearing or not wearing a helmet is a "choice", Because Vietnam is located in Southeast Asia, The climate is hot and humid, Helmets are heavy and airtight, Wearing it is very easy to cause heatstroke, Particularly in fast maneuvers, This is the easiest way to do strenuous activities such as running. Therefore, in order for the troops to fight more efficiently, There would be no mandatory order for everyone to wear a helmet, If you don't want to wear it, you can choose to wear a cloth cap with eaves. So in the vast majority of relevant historical photos, Among our troops participating in the war, The highest percentage of helmets is worn by artillery, It is mainly used to defend the fragments of enemy artillery and various hard objects brought up by explosions in artillery warfare. Even some border militiamen wore helmets in large numbers, On the contrary, the impact is at the forefront, Infantry units carrying out a large number of mobile combat missions are rarely worn, Investigate its reason, It is for the infantry troops to carry out large-scale interspersed operations frequently. Exercise is enormous, It is really inconvenient to wear helmets, This approach has both advantages and disadvantages, It is not good to judge right or wrong here, but when facing such a horrible "killer bee" on the ground on 149, it is regrettable and regrettable that the heavy casualties caused by the low wearing rate of helmets have to be said. If they had worn helmets instead of military caps like Zhang Xiaobo, the casualties caused by the sting attack of "killer bee" would have been much smaller.如此重要的承诺,岂能失信于天下?何况是各路义军对大楚的耿耿忠心,本将更不可有丝毫疏忽了。In the first season of the competition program "Charming China City", a cultural tourism brand competition program for large cities, the city has achieved remarkable results in economic and social benefits by means of "culture + tourism". On this basis, the second season program will be optimized and upgraded to further promote the transformation and upgrading of Chinese cities and present a gift to the "40th anniversary of reform and opening up" with the in-depth integration of creative ideas of "culture + tourism + city brand". The program takes the harmonious relationship between "people and the city" as its core value, pays more attention to exploring the profound cultural details of the city, reads the charm of the city from the perspective of the emotional dependence and harmonious coexistence between people and the city, tells Chinese stories well from the perspective of the city, and promotes Chinese culture.空から降ってきてパニック状態のアンノーンは「どこから来たの?」と聞いても「キラキラしたとこ」という以外分からない。 在这段期间,陈秀跟王俊涛两个失意人,互相鼓励扶持,最终给这名可怜孩子找回了一个最完美的家……
