Binary Aggregation with Integrity Constraints

Martedi' 20 Novembre 2012 - Umberto Grandi


Martedi' 20 Novembre 2012 alle ore 16:30 in aula 2BC60, il dott. Umberto Grandi (Dip. Matematica Universita' di Padova) terra' un seminario dal titolo "Binary Aggregation with Integrity Constraints".

Collective decision making problems arise when a set of individual agents need to make a choice over a set of common alternatives. A central problem in the study of these situations is that of aggregating individual expressions, such as preferences, judgments and beliefs, into a collective view, to obtain a summary of the individual views provided. A classical example is that of aggregating the result of several search engines into a common ranking.
In this talk I will focus on situations in which a set of agents each need to make a yes/no choice regarding a number of issues, and these choices then need to be aggregated into a collective choice. Inspired by potential applications in Artificial Intelligence, I will put forward a systematic and flexible framework that aims to account for the wide variety of situations that can be encountered when dealing with the problem of collective choice.
In the first part of the talk I will present the framework of binary aggregation with integrity constraints, and show how classical frameworks such as preference and judgment aggregation can be viewed as instances of this general setting. I will then list a number of directions for future research and possible extensions of this framework.
