Urgent help with attached question on last
Given a system y = Ax + e. The unknown vector x is 3 X 1, i.e., x 6 RX]. A E RNx3 has singular value decomposition A - UEVT with 100 0 0 E - 0 90 0 0 0 85 The entries of e are independent, identically distributed Gaussian with mean of zero and variance 12 ; i.e., e; ~ N(0, vz) for i = 1, ..., N. You can also assume that |x is on the order of 1-10. Suppose 1/2 ~ 10, which of the following methods will likely result in the best estimate of x? O x = VEBUTy 1/100 0 0 where R = 2 and E, = 1/90 0 0 0 0 O x = (AT A + 61) ATy where o = 10 O No answer text provided. O x = (ATA) ATy
