Decision tree is an extremely easy-to-understand algorithm. After a model is built, it is a series of nested if... else... or nested switches.
Advantages: low computing complexity, easy to understand output results, insensitive to missing median values, and the ability to process irrelevant feature data;
Disadvantages: excessive matching may occur;
Applicable data types: numeric and nominal.
Python implementation of decision tree:
(1) implement several tool functions: Calculate the entropy func
Linux C language traversal folder-general Linux technology-Linux programming and kernel information, the following is a detailed description. I learned how to traverse folders in C language in LINUX.
Several members in struct dirent:
D_type: 4 indicates a directory, and 8 indicates a file.
D_reclen: 16 indicates a subdirectory or file, and 24 indicates a non-subdirectory.
D_name: directory or file name

In the previous article (building a Nginx server in Docker), we have described how to quickly build a practical nginx server. This time around Docker mirroring (Docker image), we'll explain how to use it. Includes three parts:
Install Docker mirrors from Docker hub or other mirror source
Installing Docker mirrors from image file
Making Docker mirrors from Docker file
Find Docker Mirrors
The first step in installing Docker mirroring is to find the list of Docker mirrors you nee

This implementation uses the simplest way, not to do any data redundancy locally, the code is as follows: Public classCartservice {Private ReadOnly StaticConfirmus

Query. Skip (pageInfo. PageIndex-1) * pageInfo. PageSize). Take (pageInfo. PageSize). ToList.
2. Disable delayed loading as much as possible, and use preload and explicit loading as much as possible.
The default Generation Code of Vs enables delayed loading. This is often because some developers perform multiple queries to the database without understanding it. The following code.

But you can save the one you use most often.TryBy now you should have mastered entitiy, Scenenode, and Scenemanager. I recommend adding or removing robots from the scene based on the code above. When you're done, empty all the contents of the Createscene method and play the following code snippet:ZoomYou can zoom the grid by calling the scale method in Scenenode.
