Ridgeclassifier alpha
Webalpha : {float, ndarray of shape (n_targets,)}, default=1.0: Constant that multiplies the L2 term, controlling regularization: strength. `alpha` must be a non-negative float i.e. in `[0, inf)`. When `alpha = 0`, the objective is equivalent to ordinary least: squares, solved by the :class:`LinearRegression` object. For numerical WebIn multi-label classification, this is the subset accuracy which is a harsh metric since you require for each sample that each label set be correctly predicted. Parameters: X : array-like, shape = (n_samples, n_features) Test samples. y : array-like, shape = (n_samples) or (n_samples, n_outputs) True labels for X.
