Extras and flags are too familiar to repeat.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.陆飞，司马战歌，张小武三个性格迥异的年青人，在军营里相识。他们参军的目的各有不同：陆飞只是为了爸爸承诺的五百万奖金；司马却是想得到一个城里人的身份；而胆小懦弱的张小武却是被母亲“逼迫”入伍。其实小武母亲张丽芳已患上绝症，她这么做，是为了让儿子尽早学会独立。军营的锤炼，让这三个年青人成为生死与共的亲密战友，并携手当上了特种兵。母亲的离世，让张小武的行为变得乖僻，最终被部队除名。但陆飞和司马并不知道，性格大变的张小武其实肩负着祖国一项艰巨任务。公海拯救行动中，陆飞终于发现张小武的真实身份，危机时刻，陆飞用生命保护了小武，以及小武身上的秘密。斯琴高娃称这次主演“媒虫郝大姐”是一次令她“终生难忘的合作”。李丁、林默予、盖克、沙景昌、冯雷、杜澎、施建岚、张小燕、陈莉、柳建、颜丙燕等观众熟悉的演员也架入其中，与斯琴高娃一起演绎这段人情故事。在《戏虫金二》中，值得一提的是，在影视创作中一向处于中心地位的导演们，在《戏虫金二》中当起了配角-蔡晓晴、何群、英达、郑晓龙、吴子牛、宋照、张建栋、穆德远、斗琪等著名导演，将剧中出演他们的本行谁是你的菜，黄渤、罗志祥西游之后再度PK，为争夺娇蛮公主Angelababy “大打出手”，张国立顶个泡面头首演搞笑皇帝！《谁是你的菜》讲述了张国立饰演的父皇为自己的女儿招婿的爆笑故事，杨颖在片中饰演的公主非一般的刁蛮任性不讲理，而且古灵精怪，仗着皇上的溺爱，处处与其对着干。一会儿撒娇叫“粑粑”（在第四集），一会儿发脾气叫“昏君”，堪称史上最作死公主。静海市内，唐家先祖为保全大家英勇牺牲，只留下唯一的血脉唐宇，流落人间。身怀绝技的高手苍穹为布大局，接近唐宇收其为徒，授其武功。夏家千金夏诗涵由多次误会唐宇到被唐宇相救而心生好感，两人情感危机重重，姐妹同爱一人，前女友再次出现，展开了一段爱恨纠葛的世纪虐恋。而唐宇无意间得到一瓶药，开始卷入一场未知的迷局之中，平静的生活被打破，他开始拥有不同寻常的能力帮助他人，也逐渐探寻到自己的身世之谜。影片改编自漫画家阿桂（桂华政）的经典畅销漫画《疯了！桂宝》，讲述了桂宝和朋友们来到四川三星堆开启全新的穿越时空的探险之旅的故事开启的一段穿越时空幻想、探秘三星堆世界的欢乐冒险故事。
