If True, will return the parameters for this estimator andĬontained subobjects that are estimators. The SAGA solver supports both float64 and float32 bit arrays. New in version 0.17: sample_weight support to LogisticRegression. If not provided, then each sample is given unit weight. sample_weight array-like of shape (n_samples,) default=NoneĪrray of weights that are assigned to individual samples. Training vector, where n_samples is the number of samples and Parameters penalty of shape (n_samples, n_features) The Elastic-Net regularization is only supported by the Supports both L1 and L2 regularization, with a dual formulation only for With primal formulation, or no regularization.
The ‘newton-cg’, ‘sag’, and ‘lbfgs’ solvers support only L2 regularization Use C-ordered arrays or CSR matrices containing 64-bitįloats for optimal performance any other input format will be converted It can handle both denseĪnd sparse input. That regularization is applied by default. ‘liblinear’ library, ‘newton-cg’, ‘sag’, ‘saga’ and ‘lbfgs’ solvers. This class implements regularized logistic regression using the (Currently the ‘multinomial’ option is supported only by the ‘lbfgs’, Scheme if the ‘multi_class’ option is set to ‘ovr’, and uses theĬross-entropy loss if the ‘multi_class’ option is set to ‘multinomial’. In the multiclass case, the training algorithm uses the one-vs-rest (OvR) Logistic Regression (aka logit, Ma圎nt) classifier.
