利用机器学习预测2022年的世界杯冠军

# FIFA-World-Cup-2022 DolphinScheduler machine learning "FIFA World Cup 2022" betting workflow **YouTube**: [Predict FIFA World Cup 2022 champion and get a daily betting strategy by DolphinScheduler!](https://www.youtube.com/watch?v=pXBINJR2l5Y) In this project, we will use machine learning to **predict which country will win the FIFA World Cup 2022** and **get a betting strategy every day**. ## World Cup predictions **Here are the results of two different forecasting methods** ### Simulate 1000 World Cup qualification results based on team win probability Probability of championship ``` Brazil 0.193 Argentina 0.160 France 0.140 Spain 0.137 England 0.131 ``` The top four ``` No.1: Brazil No.2: France No.3: Argentina No.4: Belgium ``` ### Choose the team with a high probability of winning ``` No.1: Argentina No.2: France No.3: Spain No.4: Belgium ``` All competition results can be viewed in the following two files https://github.com/jieguangzhou/FIFA-World-Cup-2022/blob/workflow-pro/results/predict.txt > The above results are from the branch `workflow-pro`. This branch will train longer models and run more simulations ## Building a prediction system in three steps ### Step-1 start DolphinScheduler we can start a [Dolphinscheduler](https://dolphinscheduler.apache.org) standalone server using Docker ```shell docker run --name dolphinscheduler-standalone-server -p 12345:12345 -p 25333:25333 -d jalonzjg/dolphinscheduler-fifa ``` And then, you can log in to the DolphinScheduler at http://localhost:12345/dolphinscheduler/ui user: admin password: dolphinscheduler123  ### Step-2 submit workflow ```shell python3 -m pip install apache-dolphinscheduler==3.1.1 ``` ```shell export PYDS_HOME=./ python3 pyds.py ``` You can click the `Project` -> `FIFA`  Then, we can see 3 workflow - training: Use FLAML to train model - predict: Use the model to predict which country will win the World Cup - betting-strategy: Get betting strategy every day  ### Step-3 run workflow #### start training workflow  We can view log after the workflow had finished  #### Start predict workflow We can view log after the workflow had finished  #### Start betting strategy workflow  `$[yyyy-MM-dd]`mean dolphinscheduler will use the current year, month and day as a parameter, we can also set it to `2022-11-26` other date.
