NBC宣布续订《芝加哥烈焰》第六季。没有什么职业能比在芝加哥第51消防队当一名消防员更有压力和危险同时又令人激动了。这是一群在大多数人面临危险夺路而逃的时候挺身而出的人们。但是胜任这份工作的崇高使命也使得他们不得不付出一些个人代价。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.不过到那时候一切都为时晚矣，某些人已经坐收渔人之利。身为重案组里唯一的女性成员，简（安吉·哈蒙 Angie Harmon 饰）可一点也不输给她那些精明强干的男同事们。对于简来说，没有什么比时时保持警惕更为重要的了，她的那股子劲头，仿佛是在和整个世界作战。他亲自出马救回子夜的希望无疑大了很多，即便是遭遇危险也能全身而退，是最合适不过的。1600多年以前的东晋末年。是一个士族与平民对立，爱情自由与传统束缚不能并存的时代。
