Regression using Higher Order Polynomial feature 1 point possible (graded) Assume we have n data points in the training set {(9,y()) } where I (6),y) is the t-th training example: We want to find a non-linear regression function f that predicts y from r given by f (x;0,0) = .0 (2) +0 where () is a polynomial feature vector of some order. What (loosely) is the minimum order of 0 (z)
