WebMay 25, 2016 · Intuitively speaking, the group lasso can be preferred to the lasso since it provides a means for us to incorporate (a certain type of) additional information into our estimate for the true coefficient β ∗. As an extreme scenario, considering the following: With y ∼ N ( X β ∗, σ 2 I), put S = { j: β j ∗ ≠ 0 } as the support of β ∗. http://www.sacheart.com/
