Use GridSearchCV to tune the parameters of XGboost model
First of all, fortunately, scikit learn provides a function to help us better adjust parameters: ​sklearn.model_selection.GridSearchCV​ Interpretation of common parameters: estimator: if XGBoost is used in the competition, it is the generated model. For example: model = XGB XGBRegressor(**otherUTF-8...

Playing with jpmml's tpot+sklearn2pmml automated machine learning integration model deployment
preface It should be the first original. I didn't find it on the Internet. The overall logic is: data import - tpot automatic machine learning selects the most suitable model and data preprocessing ideas - convert to sklearn code - convert to PMML model through sklearn2pmml Library - deploy in UTF-8...
