i. (5 points) Derive the vectorized analyitical solution (also called the closed form solution): w* = [D_1] ¹ t ii. (5 points) Derive the gradient of a single parameter: N JED (w) δω; Σ{y(xn, w) - tn}xnj n=1 iii. (10 points) Vectorize the gradient to get the following formula: [y(x₁, w) - t₁ JED(w) VwED(w) [D_1] (x2, w) - t2 Əw y(xn, w) - tn = = =
