Job description
Perception and analysis of the environment around us is a major challenge in many promising industrial fields. In this context, artificial intelligence (AI) algorithms have unquestionably proven their effectiveness for vision-related tasks, using various sensors (camera, lidar...). Today, there is growing interest in the use of radar (radio detection and ranging) sensor data by AI. Radar is a sensor that stands out for the nature of its data, its operability (low light levels, bad weather, etc.) and its cost. However, it produces sparse data with low spatial resolution, making them difficult to exploit by traditional algorithms. Recently, artificial neural networks based on a graph representation of data (Graph Neural Networks - GNN) have shown good accuracy on sparse and noisy sensor data [1]. As a result, the use of GNNs to exploit radar data seems very promising [2]. The spectrum of applications is wide, from intelligent vehicles (cabin monitoring) to medical devices (vital signs measurement) and surveillance devices (fall detection).
