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.　　科特（苏利文·斯坦普莱顿 Sullivan Stapleton 饰）是一名联邦探员，他的名字亦被纹在了神秘女子的身上，因而被卷入了事件之中。上司任命科特为危机事件反应小组的组长，和同事里德（罗伯·布朗 Rob Brown 饰）、塔莎（Audrey Esparza 饰）等人一起彻查事件的来龙去脉。随着调查的深入，一个惊人的阴谋逐渐浮出了水面，为了阻止犯罪分子的行动，科特必须和神秘女子合作，因为她身上的纹身，正是化解整个案件的关键线索。Basketball二十集系列轻喜剧《起步停车》视角独特，内容新奇，以多角度全方位手法描写九十年代中期社会方光未艾的“学车热”现象，通过1194号教练车上一班性格、职业迥然不同的学员和他们校内外色彩斑阑的生活，反映了驾校怎样将一群散兵游勇式的“马路杀手”培养成观念强、守纪律的合格首都驾驶员，以一集集鲜活生动的事实，幽默而又深刻的刻画出教练员和交警们才智劳动的巨大付出和他们甘心奉献的可贵精神。How else do you say that those four people were killed?
