Updated March 23/plead (Defence)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.该剧讲述了上个世纪40年代,段胜男(黄奕饰)为了挽救濒临生存危机的玉器行和狱中的父亲,冒险去缅甸寻找好玉,途中遇险,偶然得到从上海滩跑出的向随缘(方中信饰)搭救,两人在危难中产生了感情.与此同时,爱国军阀厉军(杨子饰)也喜欢上了气质脱俗的胜男,并对她展开了狂热的追求.时间转到2000年,段...CBS正式一口气续订《小谢尔顿》（Young Sheldon）第3、4季。这意味着该剧至少会播到2021年。在后《生活大爆炸》（The Big Bang Theory）时代，CBS显然有意将其打造成下一部台柱喜剧。通常都是用来清蒸或烧汤。"Are you guilty?"
