Question 2

+3 marksOne correct option

Consider the following three weight vectors obtained by minimizing the ridge regression objective with penalty parameters λ=0.1,10,50\lambda = 0.1, 10, 50.

θ1=[0.50.562.5]T\theta_1 = \begin{bmatrix} 0.5 & 0.56 & 2.5 \end{bmatrix}^T
θ2=[0.050.11.23]T\theta_2 = \begin{bmatrix} 0.05 & 0.1 & 1.23 \end{bmatrix}^T
θ3=[1.20.843.15]T\theta_3 = \begin{bmatrix} 1.2 & 0.84 & 3.15 \end{bmatrix}^T
