Closed Form Solution For Ridge Regression - It suffices to modify the loss function by adding the penalty. Transform y to have 0. In matrix terms, the initial quadratic loss function. If data are first centered about 0, then favoring small intercept not so worrisome. I lasso performs variable selection in the linear model i has no closed form solution (quadratic programming from convex. Not unique to polynomial regression, but also if lots of inputs (d large) or, generically, lots of features (d large).
