WitrynaThe reason that logistic regression and SVM have similar performance is that the training data is linearly separable, which happens very often. Therefore, there is no need to project the value to a higher dimension to separate them. Under some situations, SVM may perform much better than logistic regression. Witryna27 kwi 2013 · The decision boundary of SVM (with or without kernel) is always linear (in the kernel space or not) while the decision boundary of the decision tree is piece-wise linear ( non-linear).
