大苞谷问：你没跟他说，我是清南村的，我家被抄了，我家住在桃花谷，有许多果树、乌龟、鸡鸭这些话？瘸腿秋霜摇头道：没跟他说。不是想发财，等情势紧张的时候，抛出来也能救急，也算做善事。For example, HTML code is as follows:洗脚城老板林东（梁家辉饰）是个好色的港商，时常找不同小姐满足生理需要。老婆王梅（金燕玲饰）不能生育，经营一家美容院，两人感情冷淡。At present, at least 19 provinces have implemented "dysmenorrhea leave", allowing female employees to rest for one or two days during special periods. However, the regulations vary from place to place. Some regulations only need to provide certificates from medical institutions, while others limit the types of work, allowing only female employees in "third-level physical labor intensity" and "long-term standing and walking work" to take "dysmenorrhea leave".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.
