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.

UNIFY: a Unified Policy Designing Framework for Solving Constrained Optimization Problems with Machine Learning

no code implementations25 Oct 2022 Mattia Silvestri, Allegra De Filippo, Michele Lombardi, Michela Milano

Our approach relies on a clever decomposition of the policy in two stages, namely an unconstrained ML model and a CO problem, to take advantage of the strength of each approach while compensating for its weaknesses.
