Sparse Regression at Scale: Branch-and-Bound rooted in First-Order Optimization
Hussein Hazimeh, Rahul Mazumder, Ali Saab
We consider the least squares regression problem, penalized with a combination of the and squared penalty functions (a.k.a. regularization). R…

Learning Sparse Classifiers: Continuous and Mixed Integer Optimization Perspectives
Antoine Dedieu, Hussein Hazimeh, Rahul Mazumder
We consider a discrete optimization formulation for learning sparse classifiers, where the outcome depends upon a linear combination of a small subset of features. Recent work has…
