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.故事讲述年轻的酿酒厂老板Jack被发现死亡,由此引发了一系列事情。他的四名员工Anna,Nancy,Louie和Cat因为一个秘密而牵扯在一起,她们约定对此保持沉默。而Anna的丈夫Max是一名警官,正在调查这起死亡事件,但他完全不知道妻子与此案有关。与此同时,四个女人的同事Tish对她们起了疑心。当今之世，还有没有国术宗师，都未可知。《喵喵请听好》为《朋友请听好》的会员衍生节目，围绕广播小站萌宠点点和苔，讲述正片外更多未播精彩内容，展示广播小站更多治愈瞬间。中国北方黄川市广播电视台新闻女主播杜若璇、市文联退伍兵转业干部卢振亭、返乡创业大学生田永青，三位青年共产党人，在不同原因下，积极响应党中央号召、主动接受了扶贫攻坚工作。他们分别来到榆州县燕山镇的三个深度贫困村，深入农户、调查摸底、精准扶贫，历经坎坷、无怨无悔，在镇村干部的帮助下，由开始抵触农村的落后转变到积极主动帮扶，坚持扶贫扶志，激发贫困村民内生动力，带领村民流转土地发展农业致富产业、实施易地搬迁扶贫、打造旅游特色小镇，把绿水青山变成了金山银山，带领村民创业共同建设美丽乡村。他们也在扶贫事业中实现了自己的人生价值，展示了最美的风采。我南雀国虽小，却是孔雀神王的后裔，不能让人小瞧了，说咱们输不起，是卑劣小人。
