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.
现在还有一个很大的担心，那就是越过到底有没有参与到此事之中？若是尹旭也出兵对付自己，那西楚国可真就是回天乏术了。
1942年夏，日军攻势凶猛，英美军队撤出缅甸，中国军队炸毁惠通桥，以怒江天险阻隔日军，滇西缅甸陷落。日军利用丛林河流等便利，加紧构筑全方位的死亡天网，意图以滇缅地区为后盾，冲破怒江防线，阻断驼峰航线，攻占全中国。一架美军飞机在撤离缅甸时遇袭坠毁，飞行员爱德华跳伞后失踪，美军派出搜救小队，不料消息泄露，小队落入日军重围，全军覆没，搜救行动失败。中国方面派出地下党员洪子杰率领的特战小队开展搜救，四名队员都是久经沙场，配合默契，有极高的军事素养和行动能力，再加上先进的美军武器极大提升了他们战斗力。四人冲破日军防线，深入敌后，在当地少数民族和转战敌后的中国军队协助下，不仅救出英军战俘和爱德华，而且找出日军在滇缅丛林中布下的死亡天网，将其一举摧毁，为滇缅反攻胜利奠定基础 [3] 。
In some first-tier cities, operators have to increase the number of 5G base stations while ensuring the operation of 4G base stations, which will increase the difficulty and financial pressure accordingly.
These continuously added wireless standards create a demand for multi-radio solutions that can cover 10 or more frequency bands. As a result, the number of RF front-ends required for digital devices has also increased. For mobile phone manufacturers, it has become a big problem to be able to control these miscellaneous devices well.
However, in the process of BLM training and consulting, what disturbed Mr. Fan Hui was that a large number of customers' enthusiasm for learning the tools greatly exceeded their attention to the values and core ideas embodied behind the tools, especially the tools introduced from large enterprises or large consulting companies. In fact, Mr. Fan Hui learned that some domestic enterprises (with a sales scale of more than 20 billion) used the "Tao Tian Tian Jiang Fa" from Sun Tzu's Art of War to make strategic plans:
