Ridge ridge alpha 1
WebThe Ridge () function has an alpha argument ( λ, but with a different name!) that is used to tune the model. We'll generate an array of alpha values ranging from very big to very small, essentially covering the full range of scenarios from the null model containing only the intercept, to the least squares fit:

WebWe will use a ridge model which enforces such behavior. from sklearn.linear_model import Ridge ridge = make_pipeline(PolynomialFeatures(degree=2), Ridge(alpha=100)) cv_results = cross_validate(ridge, data, target, cv=10, scoring="neg_mean_squared_error", return_train_score=True, return_estimator=True) WebThe optimum setting of alpha depends on the particular dataset we are using. Increasing alpha forces coefficients to move more toward zero, which decreases training set performance but might help generalization.
