NettetSo our new loss function (s) would be: Lasso = RSS + λ k ∑ j = 1 β j Ridge = RSS + λ k ∑ j = 1β 2j ElasticNet = RSS + λ k ∑ j = 1( β j + β 2j) This λ is a constant we use to assign the strength of our regularization. You see if λ = 0, we end up with good ol' linear regression with just RSS in the loss function.
