the paper. For logistic regression, regularized versions such as Elastic Net have been proposed (Zou and Hastie 2005), which consider adding a convex combination of the ℓ 1 and ℓ 2-norm penalty to the objective; however these regularized classiﬁers were not derived using tools from robust optimization. Using robust optimization, logistic
