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.安东尼·麦凯、詹米·多南加盟科幻惊悚片[同步](Synchronic，暂译)。艾伦·穆尔黑德、贾斯汀·本森([无尽])执导，贾斯汀·本森操刀剧本。麦凯、多南在片中饰演新奥尔良两名医护人员，一种离奇药物的出现导致了一系列恐怖死亡事件，两人的生活也被彻底打乱。XYZ Films负责该片国际发行。《新教宗》由《年轻教宗》团队制作，预计今年底展开拍摄。由于是「新教宗」的故事，届时演员也将替换成全新的阵容，不确定裘德洛的角色是否会再现身。根据约翰·葛林的畅销书改编，故事背景设定在圣诞前夜的一场百年一遇的暴风雪中，几个高中生发现了意想不到的机遇，也发现了考验他们友谊、爱情生活和对未来抱负的复杂因素。如果可以买下梦寐以求的爱情，你愿意拿什么交换？欢迎来到世界最大的购爱中心-爱的奥特莱斯！在这里，你能购买一个人的爱，交易成功，他会无条件地爱你，有限期限一个月，购买时，我们不使用金钱，只收……WeChat Duokaibao2.
