This is well understood. In actual development, we often encounter too many methods defined in this interface, so that sometimes we do not need them all in some implementation classes. Look at the code:
It is easy to see that OvR only needs to train N classifiers, while OvO needs to train N (N-1)/2 classifiers, so the storage overhead and test time overhead of OvO are usually larger than OvR. However, in training, each classifier of OVR uses all training samples, while each classifier of OVO only uses samples of two classes. Therefore, when there are many classes, the training time cost of OVO is usually smaller than that of OVR. As for the prediction performance, it depends on the specific data distribution, which is similar in most cases.

"No one in position 149 was completely unstung, I am no exception, He got several times during the fight, But I'm lucky, None of them stung the key parts, Two big flying wasps stung me in this area of my chest. Luckily there was a bullet bag hanging on it, The bullet bag was stuffed with four shuttles (note: the shuttle here refers to the magazine of an automatic rifle). Four shuttles covered the whole chest, So it blocked the two poison needles directly, No matter how severe the poison needle is, of course it cannot penetrate the shuttle. Just pierced the canvas on the bullet bag, It was hung on it, but although it could not be tied through the shuttle, it could still pass through the slightly thinner metal, because I had been hit several times in my head. When the battle was completely over, I had five poisonous needles on my head, each of which was the front tip already stuck in and the back half was exposed. I was wearing a helmet at that time! Even helmets can be tied up. No wonder several comrades with cloth hats have their skulls nailed through.

The appearance and behavior of being out of position again are not as admirable as the "inner show". For example, this "questioning elder sister", who comes from Australia and is named Andy, asked questions in both Chinese and English during the second meeting of the 18th National Congress of the CPC in 2012. At the same time, she also quoted classics and ancient poems, which made many reporters on the scene give thumbs-up.
This is the end of the analysis of the article. At this time, look at the Android event distribution flow chart. This chart is drawn according to the above four situations. If you understand the four situations (at least give a way to intercept consumption and think of what the log of each event looks like), then it should not be difficult to understand this chart.
