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.《小姨多鹤》是一部“苦难年代的温情故事”——讲述名叫多鹤的“日本遗孤”抗战结束后在一户普通的东北张姓人家几十年的生命历程故事。日本兵败二战，在艰难的逃亡中，垦荒团的少女多鹤依靠机智和对生的本能渴望逃过了死亡，阴差阳错被张石匠、关小脚老两口相救，张家二儿子张俭的老婆朱小环曾因日本鬼子的惊吓导致流产，从此不能生育。多鹤的介入，使得整个家庭的关系变得有故事起来。之所以有“小姨”之称，是因为张家及她对外都要掩饰其身份，那是一个特殊的年代，生下的三个孩子不能喊她妈妈。这位“小姨”一路几十年，和张家、和小环、和孩子、和行进中的社会，形影相随，情感相随，感动相随，泪水相随。四种颜色，四种性格，面对金融危机，裁员风暴，四位美女的命运将由你决定！！！为了应对愈演愈烈的温室效应，世界各国在2014年发射了代号CW-7的冷冻剂，谁知却将地球推入了万劫不复的极寒深渊。大多数的人类死于寒冷与恐慌，只有为数不多的数千人登上了威尔福德工业开发的列车，成为永不停歇的流浪者。这列火车借助威尔福德（艾德·哈里斯 Ed Harris 饰）开发的永动引擎，并且配备各种完备设施，在之后的十七年里构建了属于自己的独立生态系统，周而复始旋转在43.8万公里的漫长旅途中。生活在末尾车厢的底层人民一直饱受压迫，为了争取自由和权力，他们在过去发起过多次暴动，但无疑例外均以失败告终。这一次，拥有领袖气质的柯蒂斯（克里斯·埃文斯 Chris Evans 饰）试图找到被囚禁的安保设计师南宫民秀（宋康昊 饰），借助他之手打开通往首节车厢的重重大门，推翻威尔福德的统治。新年伊始，一场血腥革命正在进行……轻叹一声，说道：今日的事情确实突然，未曾想到越国的骑兵装备那样神奇，厉害，以至于我们猝不及防，暂时落败。Charm V5: 3001-5000 Charm Value
