Adaptive Optimization for Prediction with Missing Data

no code implementations2 Feb 2024 Dimitris Bertsimas, Arthur Delarue, Jean Pauphilet

When training predictive models on data with missing entries, the most widely used and versatile approach is a pipeline technique where we first impute missing entries and then compute predictions.

Solving the Quadratic Assignment Problem using Deep Reinforcement Learning

no code implementations2 Oct 2023 Puneet S. Bagga, Arthur Delarue

The Quadratic Assignment Problem (QAP) is an NP-hard problem which has proven particularly challenging to solve: unlike other combinatorial problems like the traveling salesman problem (TSP), which can be solved to optimality for instances with hundreds or even thousands of locations using advanced integer programming techniques, no methods are known to exactly solve QAP instances of size greater than 30.

Reinforcement Learning with Combinatorial Actions: An Application to Vehicle Routing

1 code implementation NeurIPS 2020 Arthur Delarue, Ross Anderson, Christian Tjandraatmadja

We develop a framework for value-function-based deep reinforcement learning with a combinatorial action space, in which the action selection problem is explicitly formulated as a mixed-integer optimization problem.

The Price of Interpretability

no code implementations8 Jul 2019 Dimitris Bertsimas, Arthur Delarue, Patrick Jaillet, Sebastien Martin

When quantitative models are used to support decision-making on complex and important topics, understanding a model's ``reasoning'' can increase trust in its predictions, expose hidden biases, or reduce vulnerability to adversarial attacks.

Optimal Explanations of Linear Models

no code implementations8 Jul 2019 Dimitris Bertsimas, Arthur Delarue, Patrick Jaillet, Sebastien Martin

We propose a general optimization framework to create explanations for linear models.
