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.哈哈哈哈哈，搞笑的吧，果然，渣男还是更受欢迎，尤其是有钱的。。。。令人无语的垃圾剧，浪费推哥这个帅哥了…7.4 Unqualified after thoracic organ surgery.1940年代后期，出身望族的李彤（潘虹 饰）、黄惠芬（李克纯 饰）、雷芷苓（肖雄 饰）和张嘉行（卢玲 饰）四姐妹远渡重洋，来到美国留学。49年元旦，她们在学校联谊会上，用歌声抒发对祖国亲人的思念和祝福。不久，李彤因家中巨大变故离开三个女友，谁也不知她去了哪里。李彤的男友陈寅（濮存昕 饰）苦等无着，与惠芬和其他一对新人准备结婚。李彤突然出现在了婚宴上，她近乎疯狂的装扮和举止令朋友们惊诧，原来她已和一个已婚男人同居。时光荏苒，李彤后来又和一个南美商人混在一起，并因酒后滋事关进拘留所，保释出来后，她在惠芬女儿莉莉生日后不久，又不知飘向何方去了......Frequent Code Review
