In class, we have defined the hypothesis for univariate linear regression as he(x) = 00 + 0₁x and the mean-square cost function as 1 J(00.01) - Σ (h₂(x²) — y()) ² 2m i=1 We define the following terms: m Ex0, x, y= 1Ỷy, xy= ¹ [x®y®¸ x²= ¹ [(x0)² m m m i=1 i=1 i=1 a. Show that the optimal values of the learning parameters 00 and 01 are given by: ху-ху 00 = y-x x²-x² 0₁ = ху-ху x²-x² b. What is the advantage of expressing the learning parameters in this format? =
