Multidisciplinary Institute in Artificial intelligence

DESCRIPTION

To build more trustworthy AI systems, we investigate how to produce explanations for results returned by AI systems and how to build AI algorithms with guarantees of fairness and privacy, in the setting of varied tasks such as classification, recommendation, resource allocation or matching.

ACTIVITIES

Our activities are structured by several PhD works co-supervised with team members in collaboration with academic or industrial partners : CEA LIST, Nokia Bell Labs, Naver Labs Europe, NUKKAI.
 

• Privacy and security vulnerabilities of Semantic Web (PhD funded by the chair)
• Political ads – audit, detection and impact analysis (PhD funded by the chair)
• Collaborative Transparency (PhD funded by the chair)
• Fairness in multi-stakeholder recommendation platforms (Cifre PhD with Naver Labs Europe)
• Rule learning for formal verification of Deep Neural Networks (PhD funded by CEA LIST)
• Alarm prediction in communication networks via explainable machine learning (Cifre PhD with Nokia Bell Labs)

We are also developing international collaborations, in particular within the TAILOR european network of excellence on Trustworthy AI in which we have launched coordinating research actions on explainability, privacy and fairness.

For the academic year 2021-2022, we are co-funding with TAILOR the delegation of Radu Ciucanu, who is working on secure protocols for AI algorithms on distributed data e.g., secure federated learning.
