此剧讲述了通过电话连接过去的2020年的女人和2015年的男人一起救出了被杀害的总统而发生的时空政治惊悚剧。沈梦海眉头微皱，不是因为情况不好，而是其战果太超出他的意料。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.这句话基本算是冰释前嫌了，杨长帆也无意再较劲，到底是父子，你理解我就够了。故而摆出一副冷眼旁观的姿态，悄悄观察几个当事人。Big Brother, do you think we will seriously calculate this? It is good to be optimistic about the fighting force directly. It is useless to care too much about DOTA to calculate this. After the calculation, the opposite side has gone away./peer (peeping)
