About the research centre or Inria department

The Inria Université Côte d'Azur center counts 36 research teams as well as 7 support departments. The center's staff (about 500 people including 320 Inria employees) is made up of scientists of different nationalities (250 foreigners of 50 nationalities), engineers, technicians and administrative staff. 1/3 of the staff are civil servants, the others are contractual agents. The majority of the center's research teams are located in Sophia Antipolis and Nice in the Alpes-Maritimes. Four teams are based in Montpellier and two teams are hosted in Bologna in Italy and Athens. The Center is a founding member of Université Côte d'Azur and partner of the I-site MUSE supported by the University of Montpellier.


This PhD position is hosted by INRIA at Sophia Antipolis. The PhD degree is granted by the Université Côte d'Azur (UCA) and it develops within a close collaboration between INRIA, Princeton University, and the University of Sheffield (TUOS) in the context of the ANR-funded project PARFAIT. The position is supervised by Eitan Altman and Samir M. Perlaza.


This project brings together tools from information theory, data sciences, and game theory to study the impact of information on decentralized decision making. There exist preliminary works involving these theories, but the simultaneous consideration of game and information theories to study machine learning systems is at this moment a largely uncharted territory. In a nutshell, the mathematical models existing in the realm of game theory neglect several aspects of practical machine learning systems. For instance, modelling the fact that some players might have access to different “amounts” of information due to noise or data acquisition imparments is largely neglected by most equilibrium concepts. In a nutshell, in most decision making processes, decisions are made with adversarial or partial information about the stochastic phenomena underlying the environment in which decision-makers interact. Therefore, tampering with data acquisition systems, due to addtive noisy or long delays, becomes an opportunity to steer the behavior of individuals and seek for particular outcomes that are not predicted by current game solutions. That is, information can be provided to an individual for increasing its benefit, but also, information can be withhold or distorted for penalizing individuals. Either way, this vulnerability to malicious or undesired influence represents a thread for any decentralized decision making process and thus, it must be understood and properly modeled.

Main activities

The PhD student will develop fundamental research using tools from information theory and game theory aiming at developping a mathematical theory for the study of machine learning systems withing the context of adversarial and incomplete information.
