张老太太道：那是当然。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.呃……范鄂林迟疑道：三爷，这次汉军是由汉王刘邦亲自率军出征的，并非韩信。叹了口气。住在糟屋郡粕屋町的高中3年级学生未来，从被恋人和朋友背叛的过去开始，就不能相信别人，也不能恋爱。唯一能满足孤独之心的，就是一个人用吉他唱自己最喜欢的歌。未来用SHINO这个账号名，将自己唱歌的样子发布到SNS上。Here we notice that the instance of FirstActivity is a2C5349 at the beginning, then jump to SecondActivity, which is always 5d5dd2a, and the two interfaces of taskId are the same. Finally, we pressed the return key once in SecondActivity, and directly returned to the original 5349 instance interface, that is, the first interface, as shown in the following figure:许岚考入的大学是燕京传媒大学，和陈启也是一路。
