WebGridSearchCV implements a “fit” and a “score” method. It also implements “score_samples”, “predict”, “predict_proba”, “decision_function”, “transform” and “inverse_transform” if they are implemented in the estimator used. … WebThe first and second integers are the range of the 'n_neighbors' hyperparameter that will be searched by the grid search, and the third integer is the number of values to generate in the interval [n_neighbors[0], n_neighbors[1]]. Default is [1, 50, 50]. n_folds (int): The number of cross-validation folds to use for the grid search. Default is 5. shyam associates
