Riassunto

Overlapping Coaltion Formation (OCF) is a relatively new paradigm that removes a restrictive assumption from the usual models studied in cooperative game theory, namely the assumption that agents can belong to
only one coalition at a time. Regardless, until recently the problem of uncertainty in OCF settings had been disregarded, with the focus being on studying rational behaviour from a traditional game-theoretic perspective. In this talk, I will present two recent works that initiate the study of uncertainty in OCF environments, via the computiation of probability bounds and the use of unsupervised learning techniques (in particular: probabilistic topic modelling) to enable rational agents’ decision making
in these complex domains.

This is joint work with my student Michalis Mamakos. Related papers:
