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.

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.

Data Driven VRP: A Neural Network Model to Learn Hidden Preferences for VRP

1 code implementation10 Aug 2021 Jayanta Mandi, Rocsildes Canoy, Víctor Bucarey, Tias Guns

These preferences are in the form of arc probabilities, i. e., the more preferred a route is, the higher is the joint probability.

Learn-n-Route: Learning implicit preferences for vehicle routing

no code implementations11 Jan 2021 Rocsildes Canoy, Víctor Bucarey, Jayanta Mandi, Tias Guns

Even in the case of changes in the customer sets, our method is able to find solutions that are closer to the actual routings than when using only distances, and hence, solutions that require fewer manual changes when transformed into practical routings.

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.

Interior Point Solving for LP-based prediction+optimisation

1 code implementation NeurIPS 2020 Jayanta Mandi, Tias Guns

Solving optimization problems is the key to decision making in many real-life analytics applications.

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.

Use of Artificial Intelligence to Analyse Risk in Legal Documents for a Better Decision Support

no code implementations22 Nov 2019 Dipankar Chakrabarti, Neelam Patodia, Udayan Bhattacharya, Indranil Mitra, Satyaki Roy, Jayanta Mandi, Nandini Roy, Prasun Nandy

We have developed "risk-o-meter", a framework, based on machine learning and natural language processing to review and assess risks of any legal document.
