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.

When setting up a network, the selected network cable must have flame resistance to reduce the probability of fire. Generally, the rubber outside the real network cable is flame-resistant, which is a national mandatory standard. However, fake network cables are often made of common flammable materials. When we buy network cables at ordinary times, we can also use this feature to identify the authenticity of network cables.

辛苦夫人。
Those outstanding experts can connect working memory with long-term memory, and can call up a larger capacity of working memory when performing professional activities such as piano and chess that they are familiar with. As Simon and others pointed out in their groundbreaking research report in 1973, chess masters have stored 50,000 to 100,000 chunks about chess games in this hard disk for long-term memory.
