1. Compared to ordinary least squares, ridge regression is not unbiased. 2. Both lasso and ridge regression can be interpreted as minimizing the same objective function 3. There are also several packages for the lasso and ridge regression like ) estimation procedures. 4. See, for example, the James Stein estimator ( which also drops linearity ) or ridge regression . 5. This is an advantage of Lasso over ridge regression , as driving parameters to zero deselects the features from the regression. 6. Thus, Lasso automatically selects more relevant features and discards the others, whereas Ridge regression never fully discards any features. 7. As discussed above, lasso can set coefficients to zero, while ridge regression , which appears superficially similar, cannot. 8. This provides an alternative explanation of why lasso tends to set some coefficients to zero, while ridge regression does not. 9. The computation of the optimal weights between the neurons in the hidden layer and the summation layer is done using ridge regression . 10. Many statistical learning algorithms can be expressed in such a form ( for example, the well-known ridge regression ).
