IETR, Institute of Electronics and Digital Technologies, is a joint laboratory between the CNRS (INSIS), Rennes and Nantes universities, INSA of Rennes and CentraleSupélec. It also hosts researchers associated through the hosting agreement between the University of Western Brittany, ESEO, and IFSTTAR-Nantes.

The laboratory has about 380 people, faculty members, PhD students and technical and administrative staff, located on several sites in Brittany and Pays de la Loire. The IETR has a large set of technical platforms to carry out life-size experiments.

The Rennes campus of CentraleSupélec houses 4 of the 13 teams of the laboratory.

AUT Team (Automation)

The aim of the Automation team is to develop algorithmic control and analysis solutions for large and interacting systems. Anticipating known reference trajectories and disturbances as well as taking into account constraints and multiple objectives, most activities are based on Model Predictive Control.

AIMAC Team (Artificial Intelligence for Multimodal Affective Computing

In the area of Affective Computing, the AIMAC team analyzes, synthesizes and tracks emotions. They develop tools drawn from Artificial Intelligence (Auto-encoders and GANs) applied to the fields of image, voice and text. The team offers a new way of representing emotions that makes it possible to follow a person’s emotional state over time. This real-time analysis of a user’s emotions is multimodal: it exploits the voice, speech, context, gesture and facial expressions. Current work focuses on stress detection and micro-expressions spotting and analysis in a medical context. The tools developed come from Deep Learning mainly.

Signal & Communications Dpt. (SC)

The Signal and Communications (SC) department is composed of two thematic teams: the SIGNAL team, which brings together skills in signal processing, algorithms and digital communications, and the ASIC team, which brings together skills in embedded electronic systems and architectures.
The two teams, which are multi-site and multi-institutional, are highly complementary and are based on cross-disciplinary skills ranging from circuits and architectures to signal processing algorithms for communications systems.
