Tīmeklis2024. gada 17. maijs · Loss function = OLS + alpha * summation (squared coefficient values) In the above loss function, alpha is the parameter we need to select. A low alpha value can lead to over-fitting, whereas a high alpha value can lead to under-fitting. In scikit-learn, a ridge regression model is constructed by using the Ridge class. TīmeklisThis 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)).
