The performance graph on the testing data using trained models. (a) Multiple regression algorithms from MATLAB regression learning toolbox, which showed that fine Gaussian SVM kernel has the smallest RMSE among those regressions. (b) The curve of predicted and real yield using fine Gaussian SVM (c). Residuals of predicted and real yield using fine Gaussian SVM. x-axis and y-axis presented 13 varieties and yield, respectively.
