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…
Mixed-integer linear representability, disjunctions, and Chvatal functions --- modeling implications
Amitabh Basu, Kipp Martin, Christopher Thomas Ryan +1
Jeroslow and Lowe gave an exact geometric characterization of subsets of that are projections of mixed-integer linear sets, also known as MILP-representable or MILP-…
The Strength of Multi-row Aggregation Cuts for Sign-pattern Integer Programs
Santanu S. Dey, Andres Iroume, Guanyi Wang
In this paper, we study the strength of aggregation cuts for sign-pattern integer programs (IPs). Sign-pattern IPs are a generalization of packing IPs and are of the form $\{x\in \…
