we have mentioned the constrained version of ridge regression:

we have mentioned the constrained version of ridge regression: " min ||w-y| WER s.t. ||w|2 8, (1) where Rxd and y ER". Answer the following questions. (10 points) Prove that this problem is a convex optimization problem. (20 points) Does strong duality hold? If yes, derive the KKT condition regarding the optimal solution w, for the above problem. . (Extra credit: 20 points) Does a closed-form solution exist? If yes, derive the closed-form solution. If not, can you propose an algorithm for computing the optimal solution (describe the key steps of your algorithm)?
