What are the main differences between kNN and SVM RBF?
a) kNN is a parametric model, while SVM RBF is non-parametric. b) kNN is sensitive to outliers, while SVM RBF is robust. c) kNN uses a linear decision boundary, while SVM RBF uses a non-linear one. d) kNN is a classification algorithm, while SVM RBF is for regression.
