Linear regression tuning parameters
NettetThis is where the alternate linear regression methods can excel. Because we consider all the predictors in least squares, this makes it susceptible to overfitting, as there is no penalty for adding extra predictors. Because Linear Regression doesn’t require that we tune any hyperparameters, we can fit our model using the training dataset. NettetRegression models Hyperparameters tuning. Notebook. Input. Output.

If the errors are Gaussian, the tuning parameter can be taken to be. alpha = 1.1 * np.sqrt(n) * norm.ppf(1 - 0.05 / (2 * p)) where n is the sample size and p is the number of predictors.
Nettet28. mar. 2024 · As I understand, cross_val_score is used to get the score based on cross validation. And, it can be clubbed with Lasso () to achieve regularized cross validation score (Example: here ). In contrast, LassoCV (), as it's documentation suggests, performs Lasso for a given range of tuning parameter (alpha or lambda). Now, my questions are: Nettet28. nov. 2024 · Abstract.
