Optimal regimes for algorithm-assisted human decision-making
Mats Julius Stensrud, Aaron Leor Sarvet
We consider optimal regimes for algorithm-assisted human decision-making. Such regimes are decision functions of measured pre-treatment variables and, by leveraging natural treatment values, enjoy a superoptimality property whereby they are guaranteed to o ...
2024Contextual Stochastic Bilevel Optimization
Daniel Kuhn, Andreas Krause, Yifan Hu, Jie Wang
We introduce contextual stochastic bilevel optimization (CSBO) -- a stochastic bilevel optimization framework with the lower-level problem minimizing an expectation conditioned on some contextual information and the upper-level decision variable. This fram ...
2023Decision support for the design of integrated biorefineries
A shift from fossil-based energy and products to more sustainable alternatives is essential to reduce greenhouse gas emissions and associated climate change impacts. Biomass represents a promising alternative for providing fuels and carbon-based products w ...
EPFL2023New Perspectives on Regularization and Computation in Optimal Transport-Based Distributionally Robust Optimization
Daniel Kuhn, Florian Dörfler, Soroosh Shafieezadeh Abadeh
We study optimal transport-based distributionally robust optimization problems where a fictitious adversary, often envisioned as nature, can choose the distribution of the uncertain problem parameters by reshaping a prescribed reference distribution at a f ...
2023Safety risk management in University laboratories
Risk management has become an essential element in the functioning of modern society. Correct risk identification and assessment are undoubtedly crucial to improving overall safety; nevertheless, often, it is accompanied by the wrong selection of correcti ...
EPFL2023On the Validity of Consensus
Rachid Guerraoui, Jovan Komatovic, Pierre Philippe Civit, Manuel José Ribeiro Vidigueira, Seth Gilbert
The Byzantine consensus problem involves.. processes, out of which t < n could be faulty and behave arbitrarily. Three properties characterize consensus: (1) termination, requiring correct (nonfaulty) processes to eventually reach a decision, (2) agreement ...
New York2023Decision Procedures for Power Structures
We study the decision problem for the existential fragment of the theory of power structures. We prove complexity results that parallel the decidability results of Feferman-Vaught for the theories of product structures thereby showing that the construction ...
EPFL2023Framework to evaluate the value of monitoring-technique information for structural performance monitoring
Eugen Brühwiler, Numa Joy Bertola
The management of existing civil infrastructure is becoming more crucial as a large share of bridges is approaching their theoretical end of service duration. Structural performance monitoring aims to verify bridge safety at a given time, and it should be ...
2023Relatively robust decisions
It is natural for humans to judge the outcome of a decision under uncertainty as a percentage of an ex-post optimal performance. We propose a robust decision-making framework based on a relative performance index. It is shown that if the decision maker's p ...
SPRINGER2022Overcoming decision paralysis—A digital twin for decision making in energy system design
François Maréchal, Tuong-Van Nguyen, Julia Granacher
The design of efficient energy systems, through the development of new technologies and the improvement of current ones, requires the use of rigorous process synthesis methods for generating and analysing design alternatives. We introduce a digital twin of ...
