这个复仇故事这又不仅仅个复仇故事；这也个爱情故事这又不仅仅个爱情故事；因为失去而产生恨因为恨才能持续多年怨；然而爱才唯一能抵抗心中仇恨武器化解郁结仇恨阻止伤害进行Demo Xia: I downloaded all the popular frameworks at present. I ran for the examples in different frames and looked at the results. I just thought it was good. Then I thought, well, in-depth learning is just like that. It's not too difficult. This kind of person, I met a lot during the interview, many students or just changed careers came up to talk about a demo, handwritten number recognition, CIFAR10 data image classification and so on, but you asked him how the specific process of handwritten number recognition was realized? Is the effect now good and can it be optimized? Why should the activation function choose this, can it choose another? Can you explain the principle of CNN briefly?

The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.
