Polyhedral Analysis of Quadratic Optimization Problems with Stieltjes Matrices and Indicators
Peijing Liu, Alper Atamtürk, Andrés Gómez +1
In this paper, we consider convex quadratic optimization problems with indicators on the continuous variables. In particular, we assume that the Hessian of the quadratic term is a…
Robust support vector machines via conic optimization
Valentina Cepeda, Andrés Gómez, Shaoning Han
We consider the problem of learning support vector machines robust to uncertainty. It has been established in the literature that typical loss functions, including the hinge loss,…
Bound states from the spectral Bethe-Salpeter equation
Gernot Eichmann, Andrés Gómez, Jan Horak +3
We compute the bound state properties of three-dimensional scalar theory in the broken phase. To this end, we extend the recently developed technique of spectral Dyson-Schwin…
Outlier detection in regression: conic quadratic formulations
Andrés Gómez, José Neto
In many applications, when building linear regression models, it is important to account for the presence of outliers, i.e., corrupted input data points. Such problems can be formu…
2x2 convexifications for convex quadratic optimization with indicator variables
Shaoning Han, Andrés Gómez, Alper Atamtürk
In this paper, we study the convex quadratic optimization problem with indicator variables. For the bivariate case, we describe the convex hull of the epigraph in the original spac…
