WebDecision Trees are inherently non-linear models. They are piece-wise functions of various different features in the feature space. As such, Decision Trees can be applied to a wide range of complex problems, where linearity cannot be assumed. ... Since Linear Regression is a parametric algorithm, the model can make use of this assumption to ... WebRegression and the non-parametric K-Nearest Neighborhood (KNN), Support Vector machine (SVM) and the Decision Tree (DT) have been utilized for building the models. The findings show that, for the used dataset, the linear regression is more accurate than the non-parametric models in predicting TC & TD.
