已经和项籍大哥约好了，他在河边等我们呢，快走吧。看完后，吕馨咂咂嘴，说道：我怎么觉得，青青青木说得比这个作者说得都好。In 2012, Li Lei's father was found to have advanced cancer. It took only half a year from diagnosis to death. Two years later, Li Lei's mother had a blood system problem and died after being hospitalized for a week. In the two years between the ages of 26 and 28, Li Lei lost two close relatives.……徐阶品味着嘉靖的语气与态度，再看了一眼白鹿。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.这些这片土地荒芜，正需要开发。
