Question 1: Short answer

mediumAI-checkedLinear Models & Regularization

Fit a straight line b=C+Dtb = C + Dt by least squares to the four points (t,b)=(0,0),(1,8),(3,8),(4,20)(t, b) = (0, 0), (1, 8), (3, 8), (4, 20). What is the minimum sum of squared errors E=∑i(bi−C−Dti)2E = \sum_i (b_i - C - Dt_i)^2?
