WebThis model solves a regression model where the loss function is the linear least squares function and regularization is given by the l2-norm. Also known as Ridge Regression or Tikhonov regularization. This estimator has built-in support for multi-variate regression (i.e., when y is a 2d-array of shape [n_samples, n_targets]). WebAug 19, 2024 · Let’s do the same thing using the scikit-learn implementation of Ridge Regression. First, we create and train an instance of the Ridge class. rr = Ridge (alpha=1) rr.fit (X, y) w = rr.coef_ We get the same value for w where we solved for it using linear algebra. w The regression line is identical to the one above. plt.scatter (X, y)
