If I set a vague goal and want to improve my English, I will be at a loss when practicing deliberately.那就等一等，等到这种愧疚沉淀下来，等到嘉靖闹脾气的契机。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.1949年10月1日新中国成立。人民解放军继续南下。广州解放前夜，国民党特务美制登陆舰“联荣号”溃逃台湾，途中停泊澳门内港。Today, taking advantage of Lao Ren's hardware to repeat the plot, I finally got what I wanted! !
