Problem 4 (20 Points): Constrained Optimization vs. Unconstrained Optimization in Regularized Linear Regression Use the techniques of Lagrangian multipliers (Please see Appendix E in CB). 1. 10 Points. Showing that minimizing the ordinal least square loss subject to the lp (12 or /1) norm constraint is equivalent to minimizing the p (12 or /1 ) regularized least square loss. In particular, N w min L(w) = > (f(xn; w) - tn)2, s.t., I/w/lp Sy n=1 N min L(w) = >(f(xn; w) -tn)2 + Allwllp n=1 2. 10 Points. Discuss the relationship between hyperparameters ) and y
