A Novel Robust Optimization Model for Nonlinear Support Vector Machine
Francesca Maggioni, Andrea Spinelli
In this paper, we present new optimization models for Support Vector Machine (SVM), with the aim of separating data points in two or more classes. The classification task is handle…
A Robust Twin Parametric Margin Support Vector Machine for Multiclass Classification
Renato De Leone, Francesca Maggioni, Andrea Spinelli
In this paper, we introduce novel Twin Parametric Margin Support Vector Machine (TPMSVM) models designed to address multiclass classification tasks under feature uncertainty. To ha…
A scenario-based framework for supply planning under uncertainty: stochastic programming versus robust optimization approaches
Francesca Maggioni, Florian Potra, Marida Bertocchi
In this paper we analyze the effect of two modelling approaches for supply planning problems under uncertainty: two-stage stochastic programming (SP) and robust optimization (RO).…
Sampling methods for multistage robust convex optimization problems
Francesca Maggioni, Marida Bertocchi, Fabrizio Dabbene +1
In this paper, probabilistic guarantees for constraint sampling of multistage robust convex optimization problems are derived. The dynamic nature of these problems is tackled via t…
Velocity, energy and helicity of vortex knots and unknots
F. Maggioni, S. Alamri, C. F. Barenghi +1
In this paper we determine the velocity, the energy and estimate writhe and twist helicity contributions of vortex filaments in the shape of torus knots and unknots (toroidal and p…
On the groundstate energy of tight knots
Francesca Maggioni, Renzo L. Ricca
New results on the groundstate energy of tight, magnetic knots are presented. Magnetic knots are defined as tubular embeddings of the magnetic field in an ideal, perfectly conducti…
