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.城中两大名嘴律师余英伟和李名扬在法庭上各施奇谋，针锋相对，英伟反败为胜却差点丧命，令他重新审视人生，他的转变令资深律师卢琛保另眼相看，招揽英伟加盟处理一宗富豪遗产案；名扬因债务缠身被迫回到师父沈奕和的律师行，初来乍到即与师父的女儿同是律师的沈悦勤合作，悦勤本与富家子弟宋家耀相恋多年，但家耀好大喜功，不求上进，更与悦勤好友卢小璐相交甚密，令名扬有机可乘；当遗产案正式开审，主审法官正是英伟的前妻亦是名扬的前女友陆思凝，双雄再度交锋，但他们渐渐揭发案中另有内情，关键人物竟与英伟徒弟程家明有莫大的牵连，律师行因而掀起一场生死存亡的大风暴……1943年，抗日战争进入了最艰苦卓绝的日子，区小队长高树江在北平丫髻山的山洞里宣誓入党。哥哥刚好当天娶亲，可就在新娘进村的路上，日本鬼子的飞机炸死了大哥，婚礼变成了葬礼，高老爹老泪纵横地硬逼着高树江娶了这个比他大四岁的女人。日寇开始对冀东根据地大扫荡，高树江率领区小队奋力抵抗，掩护刘家店的乡亲们转移，但高老爹和高树江的妻子高刘氏在逃难中走散，后来乡亲们说他俩被鬼子杀害在山沟里。高树江顽强地同日寇抗击直至最后一刻，抱着日本鬼子跳下了舍身崖。这一幕被远处的一个年轻女孩疙瘩看到了，于是疙瘩冒死从山崖下救活了摔成重伤的高树江。《平凡的世界》根据路遥小说《平凡的世界》改编，由SMG尚世影业、华视影视、榆林文旅、上海源存影业、乐视网联合出品当代农村剧，并由毛卫宁执导，王雷、佟丽娅 、袁弘、李小萌、刘威、尤勇、夏铭浩等人主演。詹建业，任职军装警员逾二十年，虽多次参与升职面试，却未能成功获得擢升。虽然如此，但妻子张芳仍默默在背后支持他，不时予以鼓励，令詹十分感动。可是，张芳母亲却一直对詹之工作颇有微言，不时冷嘲热讽，令两口子感到不是味儿。张母更不时劝戒张，该找个条件更好的男人付托终身。某日下午，在警署报案室当值的詹，为一名涉嫌在女厕偷拍录像之疑犯关炳文录口供。关不单否认指控，更告诉詹，他在女厕无意中发现个惊天大秘密。原来世上有个女人组织，正进行歼灭全世界男人的计划，由于计划需要秘密进行，不能泄漏任何风声，因此她们选择在没有男人的地方──洗手间──定期会面，互相交换杀男人的情报，这正好说明为何女人在洗手间所花的时间较男人长。关决心潜入女厕，搜集她们谈论集体杀害男人的证据。詹认为关之说法十分无稽，但关坚持，詹只好如实记录在案。当天晚上，警局同僚来电，说那份供词不翼而飞。詹返回警署替关再录口供时，关不单态度回异，更大方认罪，言词间似乎隐瞒着甚么似的，这反而引起詹之好奇，因此决定调查下去。詹发现当天下午女督察方子晴接触同时，大家也更加关注小鱼儿、花无缺、铁心兰三人最后到底如何收场，很多人表示纵然不看小鱼儿和花无缺的生死对决，也一定要看看这段三角恋最后如何收尾。一个偏远贫穷的小山村里，活泼善良的女娃小花，在爹娘和奶奶的呵护下，过着虽不富裕但却快乐的生活。小花娘就快生了，她爹为了多挣些钱去了黑煤窑打工。一个大雨滂沱的日子，小花爹被埋在了坍塌的煤窑里，小花娘也因为急火攻心加上淋雨引起大出血失去了生命。从此小花和瞎眼多病的奶奶过着相依为命的生活，懂事的小花用自己瘦小的身躯支撑着濒临解体的家，小花的眼泪和万般努力，最终没能留住唯一的亲人奶奶，小花从此成了孤儿。
