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.周星河？周星河来了没？就在这时，里面房间走出来一个工作人员，大声喊道。腾远学院新来的转学生颜晓希，养父曾是乒乓球高手，在养父的言传身教下，颜晓希打得一手好乒乓。颜晓希是个自立自强的女生，不仅打多份工贴补家用，还运用自身娴熟的球技参加球赛，挣取奖金交学费。腾远学院乒乓球社团社长齐景浩，是一个帅气的乒乓球高手，一次偶然他见识到颜晓希出众的球技，因此力邀颜晓希加入乒乓球社团，共同携手赢得全国学院杯冠军，颜晓希的加入让社团注入新的活力，乒乓社团日渐壮大，吸纳更多年轻的优秀球手。在一次次高手对决中，国球的竞技魅力深深感染了所有人。电视剧版《我的野蛮女友》，不仅保留了电影版的故事主线，更是继承了电影版中的一些经典桥段。牵牛和女友换鞋穿，就是很有代表性的一个。故事讲述两大高手司马纵横（刘江）与洪震（罗乐林）决战，横打败震，废其武功，将他送往无我岛教化。皇极神算姚康节算出横必会称霸，但祸害武林，横恐他泄秘，要杀他灭口。节抱其女平逃至其船上，与震同被送往无我岛，途中遇风暴沉船，横以为眾人已死而安心，实则眾人已逃往一孤岛。七年后，平（梁小冰）长大，回中原向横报仇，四出散播预言图，令横忧心，横下令捕散谣者，市井小子骆风（郭富城）无辜被牵连，为要保命，风投靠红袍侠使者兀述，因而被方靖（戴誌卫）司马秋惜（刘秀萍）夫妇误为歹人加以追刹，横为从风口中查出真相，安排他到山庄内接受感化。Sky宣布续订《#不列颠尼亚#Britannia》第三季,不过同时Amazon表示不再参与本剧,并且不会上线第二及第三季。方明（吴倩莲）是广告公司的创作总监，本来事事一帆风顺，怎知结婚在即，男友弃婚逃走，方明装作坚强前赴北京工作，认识程扬（李亚鹏）。程杨是体育学院体育队学生，有一青梅竹马女朋友邢佳妮。佳妮为了出国而跟一位香港男人有了孩子，事后此人无影无踪，佳妮把孩子生下后，另外跟随一位美藉华人去了美国，程扬一直带着佳妮的孩子，起了个名字叫小单，并且非常照顾佳妮的妹妹邢佳华（龚蓓苾）。佳华是美术学院的学生，因方明跟程杨的关系，认识方明的弟弟方正（陈豪）。方正是北京一大百货公司的买办经理，风流不羁，夜夜笙歌，但方正想不到自己竟会爱上佳华这黄毛丫头。方明因为跟上司LAKE KU（叶广俭）不和而遭解雇，位置被助手吴里婷（陈海恒）顶替，事业爱情两失意。程杨得知佳妮从美国转轧去了法国，再到了香港，决心到香港找佳妮，托方明千方百计在香港找到一份工作，并暂住在方明家。佳妮不惜伤害程杨，方明安慰关心程杨，双方遂成为莫逆之交。
