四百年前的嘉定古城，积雪未融，寒风凛冽。但在这深冬的尽头，春天带来了暖暖的气息。村中的各个角落里响起了爆竹声，小孩子们在自家门口玩耍，大人们则忙着新桃换旧符，迎接新一年的到来。过了三十是初一，一大早，嘉定名士唐时升端坐家中，而远迩学子相继赶到唐家，向老师拜年。老人不在乎来客的富贵与贫寒，只拿出自家所种的菜做成了贺年羹，让他们品尝着这个最朴素的味道。Let's first list a column in life to illustrate the following command mode: For example, we often buy things on Tmall. Then place an order, I want to receive the goods after placing the order, and hope that the goods are true. For users, it is not concerned about how the seller delivers the goods after placing the order. Of course, the seller also has time to deliver the goods, such as delivering the goods within 24 hours. Users do not care about who the express delivery is to, and of course some people will care about what the express delivery is. For users, it is only necessary to deliver the goods within the specified time and generally receive the goods within a considerable time. Of course, the command mode also includes cancellation orders and redo orders. For example, after we place an order, I suddenly don't want to buy it. I can cancel the order or place the order again (i.e. Redo the order) before delivery. For example, I took the wrong size of my clothes. I cancelled the order and took a larger size again.In order to establish a reliable cross-validation method, you must have a good understanding of the data and the challenges you face.
