Can Poverty Be Reduced by Acting on Discrimination? An Agent-based Model for Policy Making

1 code implementation3 Mar 2024 Alba Aguilera, Nieves Montes, Georgina Curto, Carles Sierra, Nardine Osman

We classify policies as discriminatory or non-discriminatory against the poor, with the support of specialized NGOs, and we observe the results in the AABM in terms of the impact on wealth inequality.

Can Interpretability Layouts Influence Human Perception of Offensive Sentences?

no code implementations1 Mar 2024 Thiago Freitas dos Santos, Nardine Osman, Marco Schorlemmer

Human Values in Multiagent Systems

no code implementations4 May 2023 Nardine Osman, Mark d'Inverno

One of the major challenges we face with ethical AI today is developing computational systems whose reasoning and behaviour are provably aligned with human values.

Value Engineering for Autonomous Agents

no code implementations17 Feb 2023 Nieves Montes, Nardine Osman, Carles Sierra, Marija Slavkovik

We argue that this type of normative reasoning, where agents are endowed with an understanding of norms' moral implications, leads to value-awareness in autonomous agents.

uHelp: intelligent volunteer search for mutual help communities

no code implementations26 Jan 2023 Nardine Osman, Bruno Rosell, Carles Sierra, Marco Schorlemmer, Jordi Sabater-Mir, Lissette Lemus

uHelp's intelligent search for volunteers is based on a number of AI technologies: (1) a novel trust-based flooding algorithm that navigates one's social network looking for appropriate trustworthy volunteers; (2) a novel trust model that maintains the trustworthiness of peers by learning from their similar past experiences; and (3) a semantic similarity model that assesses the similarity of experiences.

Value alignment: a formal approach

no code implementations18 Oct 2021 Carles Sierra, Nardine Osman, Pablo Noriega, Jordi Sabater-Mir, Antoni Perelló

Value alignment is then defined, and computed, for a given norm with respect to a given value through the increase/decrease that it results in the preferences of future states of the world.
