WebOct 25, 2014 · In this paper, we develop screening rules for overlapping group lasso. To address the challenge arising from groups with overlaps, we take into account overlapping groups only if they are inclusive of the group being tested, and then we derive screening rules, adopting the dual polytope projection approach. This strategy allows us to screen ... WebIssue of using the group-lasso group(w) = P g kw gk 2 sets groups to 0. One variable is selected ,all the groups to which it belongs are selected.
