In this problem, we will focus on the regularization (referring to week 7's slide page 19 and page 26). Supposed that the regularized weight wreg is a solution to: min: Ein(w) = 1 N X N n=1 (wxn yn) 2 subject to: w w C where is a matrix. If w lin wlin C, where wlin is the linear regression solution, then what is the regularized weight wreg? [a] wreg = wlin [b] wreg = Cwlin [c] wreg = wlin [d] wreg = Cwlin [e] wreg = wlin [f] None of the above Please select one correct option from the above options and briefly discuss your reason. Hint: wlin = (Z Z) 1Z y and wreg = (Z Z I) 1Z y
