Gridsearchcv model

WebMay 20, 2015 · 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 uses about 0.7*0.66=0.462 (46.2%) of the original data. In your second model, there is no k-fold cross-validation. WebMar 3, 2024 · GridSearchCV. It is a library function that is a member of sklearn’s model_selection package. It helps to loop through predefined hyperparameters and fit your estimator (model) on your training set.
