Cross_val_score estimator
WebJul 21, 2024 · Values for 4 parameters are required to be passed to the cross_val_score class. The first parameter is estimator which basically specifies the algorithm that you want to use for cross validation. The second and third parameters, X and y, contain the X_train and y_train data i.e. features and labels. Webcross_val_score and GridSearchCV have a n_jobs parameter defining the number of cores it can use. set it to n_jobs=-1 to use all available cores. Random Search RandomizedSearchCV works like GridSearchCV Has n_iter parameter for the number of iterations Search grid can use distributions instead of fixed lists
