Module 7: Capstone Project … 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 ... WebGrid Search with Logistic Regression¶ We will illustrate the usage of GridSearchCV by first performing hyperparameter tuning to select the optimal value of the regularization parameter C in a logistic regression model. We start by defining a parameter grid. This is a dictionary containing keys for any hyperparameters we wish to tune over. city lights judge judy
