Consider a classification problem on linearly separable data. We train an SVM model and a logistic regression model. For logistic regression (LR) we add a small regularization term (penalty on weights) in order to make the optimum well-defined. Each model gives us a margin. Consider a datapoint $\mathbf{x}_{0}$ that is correctly classified and strictly outside both margins Which one of the following statements is incorrect ?
A. There exists a direction in which we can slightly move $\mathbf{x}_{0}$ without changing the LR decision boundary after retraining.
B. $\mathbf{x}_{0}$ isn't a support vector
C. There exists a direction in which we can arbitrarily move $\mathbf{x}_{0}$ without changing the SVM decision boundary after retraining.
D. If we remove $\mathbf{x}_{0}$ from the dataset and retrain, this will change the LR decision boundary.
E. If we remove $\mathbf{x}_{0}$ from the dataset and retrain, this will not change the SVM decision boundary.
