WebDec 28, 2024 · GridSearchCV is a useful tool to fine tune the parameters of your model. Depending on the estimator being used, there may be even more hyperparameters that need tuning than the ones in this blog (ex. K-Neighbors vs Random Forest). Do not expect the search to improve your results greatly. WebJan 11, 2024 · GridSearchCV takes a dictionary that describes the parameters that could be tried on a model to train it. The grid of parameters is defined as a dictionary, where the keys are the parameters and the values are the settings to be tested.

WebGridSearchCV implements a “fit” and a “score” method. It also implements “predict”, “predict_proba”, “decision_function”, “transform” and “inverse_transform” if they are implemented in the estimator used. The parameters of the estimator used to apply these methods are optimized by cross-validated grid-search over a ... WebGridSearchCV inherits the methods from the classifier, so yes, you can use the .score, .predict, etc.. methods directly through the GridSearchCV interface. If you wish to extract the best hyper-parameters identified by the grid search you can use .best_params_ and this will return the best hyper-parameter.
