There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up). Mastering this knowledge, it is good for you to understand the cross entropy and relative entropy, which look similar but easy to confuse. At least you know why many machine learning algorithms like to use cross entropy as cost function ~Dungeons and Warriors is the forerunner of the global 2D horizontal combat online game (MMOACT).他是我爸，今天来从老家过来看我，你不要误会。　　平凡女孩江南雪在爱情友情皆受挫的情况下，机缘巧合与一个外表英俊的小混混互换身体来到男神咖啡厅，与贵公子陆河上演了一场非同寻常又充满欢乐的爱情故事。仇弟成功盗取胶卷，却也招来敌人的疯狂报复。郭天明被绑架，组织查出胶卷拍摄的是日本细菌实验的数据，日方却以郭天明作为交换胶卷的筹码。面对两难境地，仇弟勇闯虎穴，给敌人沉重打击。随着洛菲菲的到来，原本平衡且平淡的表象被彻底打破，宿命使然洛菲菲成了史上最惨穿越女主，更莫名其妙的成了弱鸡反派大boss。1. Creator: FactoryPizzaStore as defined above. It is an abstract class, which defines the method of creating objects. This method is an abstract method, and the specific process of creating objects is implemented by its subclasses. This abstract class usually relies on an abstract Product (another role in the factory method pattern) class. These abstract products are made by subclasses, and the creators do not care what kind of products are made.
