When cv=None, or when it not passed as an argument, GridSearchCV will default to cv=3. With three folds, each model will train using 66% of the data and test using the other 33%. Since you already split the data in 70%/30% before this, each model built using GridSearchCV …
WebHowever, Grid search is used for making ‘ accurate ‘ predictions. GridSearchCV. Grid search is the process of performing parameter tuning to determine the optimal values for a given model. Whenever we want to impose an ML model, we make use of GridSearchCV, to automate this process and make life a little bit easier for ML enthusiasts.
