Memory, which can be divided into two types: one is called random, which is responsible for temporarily storing data waiting for CPU processing, and the data will be lost after power failure. It has no memory function. If the CPU is compared to the carriage of a train, RAM is the platform, and the people who go up and down the train are the data waiting to be processed and can only stay on the platform temporarily. The other is called read-only device, which can only read but not write, and its contents will not be lost after power failure. We will not introduce all the other equipment in the host computer here. In short, they all perform their respective duties to make the computer run normally, thus making the computer a good helper in our work and life.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.此时，一个从来没有在启明上发过言的读者人生就如果，发出了一个长贴The above log has a total of 7 events. Although the log is very long, it is actually very simple. It is mainly divided into two categories: MyView consumed and MyView did not consume. Where x=0, 3, 5 are consumed and the others are not consumed. All events in the distribution process log are the same (as are the down events by default). It is also clear through source analysis why onInterceptTouchEvent () is called every time. The law of the consumption process is also obvious. Events with X=0, 3 and 5 will disappear when consumed, and other events that have not been consumed will be directly transmitted to the top parent View instead of being transmitted back layer by layer.The report of Xi'an Incident is another beautiful battle fought by Aban. On the day of the incident, Aban won the global exclusive news for the New York Times based on his friendship with Jiang, Song, Kong and Chen. News history often says that Zhao Minheng of Reuters was the first to report the Xi'an Incident. However, Zhao Minheng relied on his sense of smell to infer, which was at most speculation. Aban reported the personal quotations of Song Ziwen and Duan Na, which was irrefutable evidence. The discovery of this matter is extremely dramatic and also benefits from his invincible contacts. That night, he was distressed by the lack of news, so he called Song Ziwen at will. Unexpectedly, Song Ziwen had already gone out and the employer said he was going to Kong Xiangxi's house. He called Chiang Kai-shek's advisor Duan Na again. Unexpectedly, Duan Na was not in the hotel either. The secretary also said it was at Kong Xiangxi's house. He immediately went to visit Song Meiling residence. The servant said that Madame Chiang had just left and went to Kong Xiangxi's house. So far, he has smelled that something important has happened and immediately called Kong Xiangxi's home again and again. After dialing countless times, someone finally answered the phone and let him find Duan Na and Song Ziwen. Song Ziwen himself told him about Chiang Kai-shek's detention. A great news, an incomparable exclusive news, was born so quickly. Matsumoto has a special section in "Shanghai Times" to describe the incident, "Assisting the new york Times." He wrote: "This is the first report of a foreign news agency Shanghai reporter on the Xi'an Incident."这会子这么亲密，一会又怎么办呢？项庄舞剑意在沛公的时候，项伯又会作何反应呢？只怕到时候，项羽和项庄都会对这个亲叔叔大跌眼镜。WeChat web page version, connect keyboard, quickly enter WeChat life.
