Problem 1 This problem focuses on fitting a piecewise affine function to data. (1.1) With data s in Table 1, find the minimum value of U, defined by U (s) = = (8 - SK)?. (1) k=1 Find the point s* and the value U (s*) such that U (s*) [B. (1x - 7) + a - 5x]?. (4) Find (o*, 8*) and the value F (a*, 3") with F(a*, 8')
