NettetPolynomial models for curves are given by. where n + 1 is the order of the polynomial, n is the degree of the polynomial, and 1 ≤ n ≤ 9. The order gives the number of coefficients to be fit, and the degree gives the highest power of the predictor variable. In this guide, polynomials are described in terms of their degree. NettetIf k is the number of classes, we generate k(k-1)/2 models, each of which involves only two classes of training data. According to Yuan et al. (2012) , one-versus-one is not practical for large-scale linear classification because of the huge space needed to store k(k-1)/2 models.
