From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:

OvO pairs the N classes in pairs to generate N (N-1)/2 binary classification tasks. For example, OvO will train a classifier to distinguish classes Ci and Cj. The classifier takes the Ci class sample in D as a positive example and the Cj class sample as a counterexample. In the testing phase, the new samples will be submitted to all classifiers at the same time, so we will get N (N-1)/2 classification results, and the final results can be generated by voting: that is, the category that is predicted most is taken as the final classification result. Figure 3.4 shows a schematic diagram.
This principle means that there are no methods in each interface that subclasses cannot use but must implement. If not, the interface must be split. It is better to use multiple isolated interfaces than to use a single interface (an interface where multiple interface methods are assembled into one).

But in that case, Not even considering so many dangers, This performance of '74 spray' is of great use, I remember there were 4 '74 spray' on the position at that time, There are two recruits who operate them. Two veterans, Both veterans were squad leaders, All have the skills of air injection, Facing the big wasp descending from the pavement, The two of them were obviously forced to hurry, Take up the '74 spray' and aim at the position where the big wasp is relatively concentrated in the sky and spray it out. If it weren't for the critical situation at that time, the two squad leaders would definitely not have this kind of "dangerous operation", while the other two recruits watched the veterans take the lead and learned to do so. Although they had not received relevant training and the accuracy of spraying was not as good as that of veterans, they finally sprayed out and did not hurt themselves or other comrades in arms.
