WebThe GridSearchCV instance implements the usual estimator API: when “fitting” it on a dataset all the possible combinations of parameter values are evaluated and the best combination is retained. Examples: See Custom refit strategy of a grid search with cross-validation for an example of Grid Search computation on the digits dataset. WebSep 11, 2024 · Part II: GridSearchCV. As I showed in my previous article, Cross-Validation permits us to evaluate and improve our model.But there is another interesting technique …
