Decision-Focused Learning: Foundations, State of the Art, Benchmark and Future Opportunities

1 code implementation25 Jul 2023 Jayanta Mandi, James Kotary, Senne Berden, Maxime Mulamba, Victor Bucarey, Tias Guns, Ferdinando Fioretto

Decision-focused learning (DFL) is an emerging paradigm in machine learning which trains a model to optimize decisions, integrating prediction and optimization in an end-to-end system.

Score Function Gradient Estimation to Widen the Applicability of Decision-Focused Learning

no code implementations11 Jul 2023 Mattia Silvestri, Senne Berden, Jayanta Mandi, Ali İrfan Mahmutoğulları, Maxime Mulamba, Allegra De Filippo, Tias Guns, Michele Lombardi

Our experiments show that by using SFGE we can: (1) deal with predictions that occur both in the objective function and in the constraints; and (2) effectively tackle two-stage stochastic optimization problems.

Stochastic Optimization

Probability estimation and structured output prediction for learning preferences in last mile delivery

no code implementations25 Jan 2022 Rocsildes Canoy, Victor Bucarey, Yves Molenbruch, Maxime Mulamba, Jayanta Mandi, Tias Guns

Results show that the zone transition probability estimation performs well, and that the structured output prediction learning can improve the results further.

Decision-Focused Learning: Through the Lens of Learning to Rank

1 code implementation7 Dec 2021 Jayanta Mandi, Víctor Bucarey, Maxime Mulamba, Tias Guns

In the last years decision-focused learning framework, also known as predict-and-optimize, have received increasing attention.

Contrastive Losses and Solution Caching for Predict-and-Optimize

2 code implementations10 Nov 2020 Maxime Mulamba, Jayanta Mandi, Michelangelo Diligenti, Michele Lombardi, Victor Bucarey, Tias Guns

Many decision-making processes involve solving a combinatorial optimization problem with uncertain input that can be estimated from historic data.

Hybrid Classification and Reasoning for Image-based Constraint Solving

1 code implementation24 Mar 2020 Maxime Mulamba, Jayanta Mandi, Rocsildes Canoy, Tias Guns

We explore the trade-off between the power of the classifier and the power of the constraint reasoning, as well as further integration through the additional use of structural knowledge.
