NettetParameters: estimator estimator object implementing ‘fit’ The object to use to fit the data. X array-like of shape (n_samples, n_features) The data to fit. Can be for example a list, or an array. y array-like of shape (n_samples,) or (n_samples, n_outputs), default=None. The target variable to try to predict in the case of supervised learning. NettetHopefully, this problem of finding the best parameters values (i.e. that result in the lowest error) can be solved without the need to check every potential parameter combination. Indeed, this problem has a closed-form solution: the best parameter values can be found by solving an equation. This avoids the need for brute-force search. calvin rodwell school baltimore
