FEBR: Expert-Based Recommendation Framework for beneficial and personalized content

no code implementations17 Jul 2021 Mohamed Lechiakh, Alexandre Maurer

The framework exploits the demonstrated trajectories of an expert (assumed to be reliable) in a recommendation evaluation environment, to recover an unknown utility function.

Removing Algorithmic Discrimination (With Minimal Individual Error)

no code implementations7 Jun 2018 El Mahdi El Mhamdi, Rachid Guerraoui, Lê Nguyên Hoang, Alexandre Maurer

We first solve the problem analytically in the case of two populations, with a uniform bonus-malus on the zones where each population is a majority.

Virtuously Safe Reinforcement Learning

no code implementations29 May 2018 Henrik Aslund, El Mahdi El Mhamdi, Rachid Guerraoui, Alexandre Maurer

We show that when a third party, the adversary, steps into the two-party setting (agent and operator) of safely interruptible reinforcement learning, a trade-off has to be made between the probability of following the optimal policy in the limit, and the probability of escaping a dangerous situation created by the adversary.

Dynamic Safe Interruptibility for Decentralized Multi-Agent Reinforcement Learning

no code implementations NeurIPS 2017 El Mahdi El Mhamdi, Rachid Guerraoui, Hadrien Hendrikx, Alexandre Maurer

We give realistic sufficient conditions on the learning algorithm to enable dynamic safe interruptibility in the case of joint action learners, yet show that these conditions are not sufficient for independent learners.
