A Method for Learning Value Systems in Generative AI
Andrés Holgado-Sánchez, Holger Billhardt, Sascha Ossowski
Value-aware AI systems require explicit computational representations of human values (groundings) and their aggregation into value systems in order to align their decisions with o…
Learning the Value Systems of Societies with Preference-based Multi-objective Reinforcement Learning
Andrés Holgado-Sánchez, Peter Vamplew, Richard Dazeley +2
Value-aware AI should recognise human values and adapt to the value systems (value-based preferences) of different users. This requires operationalization of values, which can be p…
Learning the Value Systems of Agents with Preference-based and Inverse Reinforcement Learning
Andrés Holgado-Sánchez, Holger Billhardt, Alberto Fernández +1
Agreement Technologies refer to open computer systems in which autonomous software agents interact with one another, typically on behalf of humans, in order to come to mutually acc…
Learning the Value Systems of Societies from Preferences
Andrés Holgado-Sánchez, Holger Billhardt, Sascha Ossowski +1
Aligning AI systems with human values and the value-based preferences of various stakeholders (their value systems) is key in ethical AI. In value-aware AI systems, decision-making…
Algorithms for learning value-aligned policies considering admissibility relaxation
Andrés Holgado-Sánchez, Joaquín Arias, Holger Billhardt +1
The emerging field of \emph{value awareness engineering} claims that software agents and systems should be value-aware, i.e. they must make decisions in accordance with human value…
Bike3S: A Tool for Bike Sharing Systems Simulation
Alberto Fernández, Holger Billhardt, Sascha Ossowski +1
Vehicle sharing systems are becoming increasingly popular. The effectiveness of such systems depends, among other factors, on different strategic and operational management decisio…
Towards a prioritised use of transportation infrastructures: the case of vehicle-specific dynamic access restrictions to city centres
Holger Billhardt, Alberto Fernández, Pasqual Martí +2
One of the main problems that local authorities of large cities have to face is the regulation of urban mobility. They need to provide the means to allow for the efficient movement…
Streamlining Advanced Taxi Assignment Strategies based on Legal Analysis
Holger Billhardt, José-Antonio Santos, Alberto Fernández +3
In recent years many novel applications have appeared that promote the provision of services and activities in a collaborative manner. The key idea behind such systems is to take a…
Smart Recommendations for Renting Bikes in Bike Sharing Systems
Holger Billhardt, Alberto Fernández, Sascha Ossowski
Vehicle-sharing systems -- such as bike-, car-, or motorcycle-sharing systems -- have become increasingly popular in big cities in recent years. On the one hand, they provide a che…
Agreement Technologies for Coordination in Smart Cities
Holger Billhardt, Alberto Fernández, Marin Lujak +1
Many challenges in today's society can be tackled by distributed open systems. This is particularly true for domains that are commonly perceived under the umbrella of smart cities,…
Taxi dispatching strategies with compensations
Holger Billhardt, Alberto Fernández, Sascha Ossowski +2
Urban mobility efficiency is of utmost importance in big cities. Taxi vehicles are key elements in daily traffic activity. The advance of ICT and geo-positioning systems has given…
Legal and ethical implications of applications based on agreement technologies: the case of auction-based road intersections
José-Antonio Santos, Alberto Fernández, Mar Moreno-Rebato +3
Agreement Technologies refer to a novel paradigm for the construction of distributed intelligent systems, where autonomous software agents negotiate to reach agreements on behalf o…
An Overview of a Break Assignment Problem Considering Area Coverage
Marin Lujak, Álvaro Garcia Sánchez, Miguel Ortega Mier +1
Prolonged focused work periods decrease efficiency with related decline of attention and performance. Therefore, emergency fleet break scheduling should consider both area coverage…
