4. In this question, we fit two models: using L2 loss. The superscript S is to denote a Simple Linear Regression (SLR) and O is used to denote a Ordinary Least Square (OLS) with two features, respectively. The data are given below: y = 0 + 0x₁ y = 00 +0x₁+02x₂ S = y -1 3 4 bias 1 ₂ 1 -1 0 1 1 1 -2 (a)Find and using the formulas derived in lecture 10 (ê$ = rº and -). Specify which x you are using and show all steps. You may find it helpful to keep intermediate steps in the square root (they cancel out nicely at the end!). 1 1
