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.What you see today is that I am no longer the same as I was three years ago when I was only Nuo Nuo and was jittery. These certificates of honor may be another kind of proof. However, I still have a long way to go in my speech and there is still too much room for improvement.《家有儿女》采用重组家庭作为故事展开的平台。生活在同一屋檐下的这一家五口，由于性格各异、习惯各异，孩子和父母之间、孩子们中间、父亲和母亲中间，难免有争执和冲突，再加上他们的爷爷、姥姥、生父、生母时常介入，更是“你方唱罢我登场”，热闹非凡，情趣连连。在形式风格上，该剧喜剧色彩浓郁，人物语言幽默诙谐，富有个性，剧情让人忍俊不禁，在不知不觉中，将观众带入捧腹大笑的情境。该剧是讲述在聚光灯背后操纵这个世界的真实政治玩家们的危险赌局，将描写指向权力顶点的超级辅佐官张泰俊的炙热的生存故事。现在大王是有意将功劳往那几个人手上送啊……说明白点，我，李斯和章邯在朝中身居高位，秦系在朝中的分量太重了。红军转移时阻击战中，赵大刀做为连长接到马起义团长下达的任务：坚守阵地七天七夜。在第六天的时候，赵大刀带领的的整个连全部阵亡，身为连长的他却死里逃生，幸免一难。任务没有完成，但他坚信组织还存在，红军绝不可能就这样灭亡。怀着满心的愧疚，他决定找到组织接受处分。在寻找部队的过程中，与离家出逃的赵果柳梅不期而遇，在投奔延安的过程当中，赵大刀与赵果结下了生死的友谊。到达马家堡。赵大刀与马起义重逢。战友情谊再度被点燃。赵果，柳梅被分到抗大学习。团长王遵义也被分到抗大学习。通过赵大刀，马起义认识了年轻秀气的赵果，并深深地爱上了这个女孩子。这使得赵大刀心里七上八下。同时，与赵果同来学习的王遵义也插了进来。国民党团长曾信雄来此商谈作战计划，赵果的出现让曾信雄眼前一亮。马王曾赵，四个男人，一个女人，就这样纠缠起来。于是，一场激烈的“爱情大战”在这里上演。后来，马起义，王遵义，曾信雄三个团长携手打日本，之间结下了是深深的战友情。一次，马起义的爱马被日军俘了去，赵大刀勇敢救马。抗日结束后，内战铺面而来。曾信雄战漆黑的夜里，史密斯（克里夫•欧文 Clive Owen 饰）无意中被卷入了一场黑帮的追杀，穿越激烈的枪林弹雨，他解救了一个在襁褓中的婴儿。婴儿的啼哭，让这个功夫了得的铁汉遭遇了难言的尴尬。除了在超市购置婴儿用品之外，他还得解决婴儿的喂奶问题。这时，他想到了在妓院工作的朋友DQ（莫妮卡•贝鲁奇 Monica Bellucci 饰），并强行赶走了嫖客，把婴儿托付给她。DQ其实对史密斯怀有深情，却一直没有机会表白。在蜂拥而至的黑帮暴徒来临之际，两人终于坦诚相见，并肩作战，照顾婴儿。经过史密斯的调查，他们发现想要加害婴儿的黑帮其实跟军火商有关系，而且他们还雇佣了很多代孕妈妈。史密斯隐隐觉得这背后隐藏着一个不可告人的秘密，于是他决定铤而走险，一场正邪较量由此展开……
