Teams & Partners

LIMPID (Leveraging Interpretable Machines for Performance Improvement and Decision) is a three-year interdisciplinary research program started in December 2020. It is conducted by Télécom Paris and IDEMIA, and funded in part by the French National Research Agency (ANR). Idemia is scientific coordinator of the project.

Télécom Paris

All academic researchers implied in LIMPID come from Télécom Paris’ research teams, affiliated either to LTCI or I3.
LTCI (Laboratoire Traitement et Communication de l’Information) is the main research lab at Télécom Paris.
I3 (Interdisciplinary Institute on Innovation) is a joint research CNRS unit (UMR9217) with teams from Mines
ParisTech, Télécom Paris and École Polytechnique.

Florence d’Alché-Buc

Full professor - holder of the Data Science & Artificial Intelligence
for Digitalized Industry & Services Chair

Her research spans a large spectrum of topics in Machine Learning, including structured prediction, representation learning, links between kernel and deep neural machines, robust and explainable learning.
Within LIMPID, she coordinates the scientific contributions of LTCI scientifics and conduct researches devoted to model’s prediction reliability and explainability by design with Pavlo Mozharovskyi.
She led LabEx DigiCosme until the end of 2019 and was program co-chair of NeurIPS 2019, and senior area chair for ICML 2021 and Neurips 2021. She currently holds the Research and Teaching Chair on Data Science and Artificial Intelligence for digitalized industry and services. She has about 100 publications, in international journals, conferences or books and co-edited 3 books in the domain.

Winston Maxwell

Director of law and digital technology studies -
Co-director of the “Operational AI Ethics” program at Télécom Paris

Previously, he was a partner at the law firm Hogan Lovells, specializing in data law. He is a graduate of Cornell Law School and obtained a PhD in economics from Télécom Paris. His research work is focused on the regulation of artificial intelligence. In 2019 he was named lawyer of the year by Les Echos/Best Lawyers in data protection law, and in telecommunication regulation. Winston Maxwell has extensive experience in regulatory and fundamental rights requirements for new technologies, having worked extensively with ARCEP, CSA, CNIL, HADOPI, the Conseil d’État and the European Court of Justice on regulatory aspects of new digital technologies. Winston was a member of the National Assembly’s Commission on Fundamental
Rights in the Digital Age, and is a member of the CSA Lab, the think-tank of the French regulatory authority for broadcasting and media.

Pavlo Mozharovskyi

Associate professor

After having finished his studies at Kyiv Polytechnic Institute in automation control and informatics, he obtained a PhD degree at the University of Cologne in 2014, where he conducted research in nonparametric and computational statistics and classification. He has been a postdoc at Agrocampus Ouest in Rennes with the Centre Henri Lebesgue for a year working on imputation of missing values, and then joined the CREST laboratory at the National School of Statistics and Information Analysis. His main research interests lie in the areas of statistical data depth function, classification, computational statistics, robust statistics, missing values, and data envelopment analysis.

Jayneel Parekh

PhD student

Jayneel Parekh completed his PhD in machine learning at Telecom Paris (Institut Polytechnique de Paris), under the supervision of Prof. Florence d’Alche and Prof. Pavlo Mozharovskyi. He worked on developing interpretation methods for deep neural networks with applications to audio and image classification. Prior to his PhD, he completed his bachelors and masters in electrical engineering at IIT Bombay. His research interests span across domains of interpretable machine learning, computer vision and machine listening. In particular, the use of semantic representations for machine learning applications to audio, vision and interpretability.

Mélanie Gornet

PhD student

Mélanie Gornet is a doctoral student at Télécom Paris, Institut Polytechnique de Paris, where she focuses on regulation of artificial intelligence that encompasses social, legal and technical aspects. Her current projects focus on the standardisation and operational implementation of ethical criteria for AI systems, such as explainability and fairness. She is particularly interested in the compliance of AI systems in the context of the proposed European AI Act regulation.
She previously studied at SciencesPo Paris and ISAE-SUPAERO, specializing in AI and data science, and accompanied the working group on facial and behavioural recognition of the Comité National Pilote d'Ethique du Numérique (CNPEN).

French National Research Agency

The French National Research Agency (ANR—Agence Nationale de la Recherche), founded in 2005 to promote French project-based research and to stimulate innovation, is a public administrative institution under the authority of the French Ministry of Higher Education, Research and Innovation. The agency funds project-based research carried out by public operators cooperating with each other or with private companies.

The LIMPID project has been granted a three-years funding through the Generic Call for Proposals 2020, under the “Artificial Intelligence” section: Projet-ANR-20-CE23-0028.

Ecosystem

The results of LIMPID will directly contribute to guidelines and requirements that will be issued by government regulators at international level in the future, in connection with trustworthy Artificial Intelligence.

IDEMIA is engaged in various working groups with the World Economic Forum, as part of an initiative led by the Ministry of Foreign Affairs, to outline the contours of a “soft law” approach, complementary to the legislative systems in place, for a responsible deployment of facial recognition.

These working groups have already led to the publication of a responsible action framework for facial recognition in the case of passenger flow management, “seeking to address the need for a set of concrete guidelines to ensure the trustworthy and safe use of this technology”. The work of these working groups continues both on pilot operations to implement the principles evoked by the framework for action, and the extension to other subjects.

IDEMIA is involved both in the definition of these action frameworks, and in their operational implementation with public and private principals.
