Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:

Diao Shen Xia: This kind of person may not be limited to running a few demo. He has also made some adjustments to the parameters in the model. No matter whether the adjustment is good or not, he will try it first. Each one will try. If the learning rate is increased, the accuracy rate will decrease. Then he will reduce it. The parameter does not know what it means. Just change the value and measure the accuracy rate. This is the current situation of most junior in-depth learning engineers. Of course, it is not so bad. For Demo Xia, he has made a lot of progress, at least thinking. However, if you ask why the parameter you adjusted will have these effects on the accuracy of the model, and what effects the adjustment of the parameter will have on the results, you will not know again.

At present, the clues of the investigation of the case are all concentrated on the two bank cards recovered. The bank cards of the rural credit cooperatives belong to the female victims, and the amount on the cards is very small. On the evening of May 14, the money on the card was taken out of a total of 11,000 yuan six times. In the bank's surveillance video, investigators found that at 9: 32 p.m. On May 14, a man wearing a woman's hooded coat entered the surveillance area. After identification, the coat was the clothes of the female victim. What makes people angry is that every time the cash is withdrawn from the ATM, the suspect cannot hide his excitement and cannot help laughing. Unfortunately, when the suspect left the ATM, he could not be found in the outdoor surveillance.
