Test RRMSE with Different Correlation Structures. Test Relative Root Mean Squared Error (RRMSE) with Different Models and Different Correlation Structures: L - linear; p2 - second order polynomial kernel; p3 - third order polynomial kernel; and rbf - radial basis function kernel. The upper panels show the performance with the linear model (k = 1) and the lower panels show the performance with quadratic model(k = 2).
