这……梁知府眉头深皱。这时，武侠小说新秀作者，同时也是新一代武侠小说作者的领军人物紫月剑的一篇文章，吸引了大众的注意力。Originated from the United States.台北一家私立医院林院长的儿子文祥。碍于父命，进山到一座与林家有世交的尼姑庵去温课。一天傍晚，文祥正在洗浴，突然一女子一闪不见了，并扔下一句恼怒的训斥。这女子名叫素碧。日后，素碧在文祥面前总是一脸冰霜。晌午时分，黎水和林聪值守归来，在树林里挖了不少蝉蛹。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.
