Regression using Higher Order Polynomial feature point graded Assume we have n data points in the training set xt ytt n where xt yt is the tth training example: A biochemist is considering the depicted data and we're helping them.We want to find a nonlinear regression function f that predicts y from x given by fx ; theta theta theta xtheta where x is the polynomial feature vector that includes all and only the monomials of degree at most k in this case, since x has dimension this means has k components; the degree component is redundant with the bias term theta but that doesn't matter for this problem What degree k would you recommend the biochemist use? Note that this is a soft, notcompletelymathematical question, much like the question, 'Does Louisiana look more like a boot or a mitten? there's consensus here among folks who know the terms involved, even though it's a soft question. Common sense and human experience are important in ML engineering, so this question is fair game.
