For example, in the semiconductor industry, Li Qiang has on many occasions asked Shanghai authorities to attach importance to the development of integrated circuits and strive to make new breakthroughs as soon as possible on the basis of the existing ones. "The more areas that reflect the country's competitiveness, the more Shanghai will take the lead in planning and focusing on tackling tough problems."For codes of the same length, theoretically, the further the coding distance between any two categories, the stronger the error correction capability. Therefore, when the code length is small, the theoretical optimal code can be calculated according to this principle. However, it is difficult to effectively determine the optimal code when the code length is slightly larger. In fact, this is an NP-hard problem. However, we usually do not need to obtain theoretical optimal codes, because non-optimal codes can often produce good enough classifiers in practice. On the other hand, it is not that the better the theoretical properties of coding, the better the classification performance, because the machine learning problem involves many factors, such as dismantling multiple classes into two "class subsets", and the difficulty of distinguishing the two class subsets formed by different dismantling methods is often different, that is, the difficulty of the two classification problems caused by them is different. Therefore, one theory has a good quality of error correction, but it leads to a difficult coding for the two-classification problem, which is worse than the other theory, but it leads to a simpler coding for the two-classification problem, and it is hard to say which is better or weaker in the final performance of the model.若是不忌嘴，六腑不清，五脏不宁，搽什么仙药都没用。主要讲述一位父亲为救女儿，与为长生不老需要彼此的器官的两个克隆人之间发生的悬疑惊悚故事。还差几票就加三更了，加油哟。他才走几步，还没下去塘底子呢，就一个趔趄坐在泥地里，引得上上下下人哄笑不绝。
