Decision-focused predictions via pessimistic bilevel optimization: a computational study

no code implementations29 Dec 2023 Víctor Bucarey, Sophia Calderón, Gonzalo Muñoz, Frederic Semet

In this work, we contribute to recent efforts in producing \emph{decision-focused} predictions, i. e., to build predictive models that are constructed with the goal of minimizing a \emph{regret} measure on the decisions taken with them.

Bilevel Optimization

Computational Tradeoffs of Optimization-Based Bound Tightening in ReLU Networks

no code implementations27 Dec 2023 Fabian Badilla, Marcos Goycoolea, Gonzalo Muñoz, Thiago Serra

The use of Mixed-Integer Linear Programming (MILP) models to represent neural networks with Rectified Linear Unit (ReLU) activations has become increasingly widespread in the last decade.

When Deep Learning Meets Polyhedral Theory: A Survey

no code implementations29 Apr 2023 Joey Huchette, Gonzalo Muñoz, Thiago Serra, Calvin Tsay

In the past decade, deep learning became the prevalent methodology for predictive modeling thanks to the remarkable accuracy of deep neural networks in tasks such as computer vision and natural language processing.

Principled Deep Neural Network Training through Linear Programming

no code implementations ICLR 2019 Daniel Bienstock, Gonzalo Muñoz, Sebastian Pokutta

Our results provide a new perspective on training problems through the lens of polyhedral theory and reveal a strong structure arising from these problems.
