Web8.Boosting decision stumps can result in a quadratic decision boundary. False. The sign of a nite linear combination of decision stumps always results in a piecewise linear decision boundary. 9.Decision trees are generative classi ers. False. Decision trees do not assume a model for the input feature distribution, hence are not generative.
