Building an interoperable, distributed storage and authorization system
Sara Bertocco, Brjan Major, Patrick Dowler +3
A joint project between the Canadian Astronomy Data Center of the National Research Council Canada, and the italian Istituto Nazionale di Astrofisica-Osservatorio Astronomico di Tr…
Sparse principal component analysis and its -relaxation
Santanu S. Dey, Rahul Mazumder, Marco Molinaro +1
Principal component analysis (PCA) is one of the most widely used dimensionality reduction methods in scientific data analysis. In many applications, for additional interpretabilit…
Lower bounds on the lattice-free rank for packing and covering integer programs
Merve Bodur, Alberto Del Pia, Santanu S. Dey +1
In this paper, we present lower bounds on the rank of the split closure, the multi-branch closure and the lattice-free closure for packing sets as a function of the integrality gap…
Characterization of the Split Closure via Geometric Lifting
Amitabh Basu, Marco Molinaro
We analyze split cuts from the perspective of cut generating functions via geometric lifting. We show that -cuts, a natural higher-dimensional generalization of the -cuts of…
Minimal cut-generating functions are nearly extreme
Amitabh Basu, Robert Hildebrand, Marco Molinaro
We study continuous (strongly) minimal cut generating functions for the model where all variables are integer. We consider both the original Gomory-Johnson setting as well as a rec…
