Piecewise Polynomial Regression of Tame Functions via Integer Programming

no code implementations22 Nov 2023 Gilles Bareilles, Johannes Aspman, Jiri Nemecek, Jakub Marecek

We consider approximating so-called tame functions, a class of nonsmooth, nonconvex functions, with piecewise polynomial functions.

Taming Binarized Neural Networks and Mixed-Integer Programs

no code implementations5 Oct 2023 Johannes Aspman, Georgios Korpas, Jakub Marecek

There has been a great deal of recent interest in binarized neural networks, especially because of their explainability.

Riemannian Stochastic Approximation for Minimizing Tame Nonsmooth Objective Functions

no code implementations1 Feb 2023 Johannes Aspman, Vyacheslav Kungurtsev, Reza Roohi Seraji

In many learning applications, the parameters in a model are structurally constrained in a way that can be modeled as them lying on a Riemannian manifold.
