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."Their attack capabilities are becoming more and more complex and elusive, and it is even difficult for security personnel to find out which IT stacks are their targets," she explained.我会在SP剧中实现那个约定。顿了一下道：没想到事情远远不止如此，因为此时得罪了赵高，引来数千秦军围剿。北宋末年，徽宗小女儿婀娜公主自己到翰林院选了年轻太学士谭义进宫为师并爱上了他，不料谭义刺杀奸臣蔡京未遂亡命天涯。宋徽宗令婀娜远嫁西夏，婀娜却让贴身婢女紫竹替代自己，不料前来相亲的西夏王子却对“假婀娜”一见钟情。婀娜抗旨出宫，带着紫竹，直赴闽南安溪寻找自己心爱的谭公子。西夏王子欲一睹婀娜深爱之人的面目，一路跟踪“假婀娜”，也来到闽南安溪。蔡京派杀手千里跟随婀娜，设下重重陷阱捕杀谭义，婀娜拼死相救。怎奈谭义在家乡已有指腹为婚却未过门的茶女--花溪女，三人在官府的追杀中躲避进深山一座小木屋，婀娜溪女谁都不肯退出情场。为诱谭义露面，蔡京命人将谭义父母尽数杀害，溪女不顾生死，与形似谭义的提线傀儡拜堂成亲并以谭家媳妇的身份送葬。婀娜为溪女义举震撼，忍痛将谭义托负给溪女，自己欲循入空门。闽南斗茶大会，为刺杀蔡京，谭义中计陷蔡京之手，存亡之际，婀娜以公主身份救下谭义。蔡京派人毒杀谭义，溪女为救谭义中毒，临终前复将谭义托负给婀娜，婀娜却无语而去……Be steadfast and steady:In the achievement of this famous Wulin hostel, the award has the word title at the end.
