Machine Learning @ the Extreme Edge

Principal investigator: dr. ir. J. R. Verbiest

Today's challenges are real-time and energy-efficient information extraction and processing at the edge using Artificial Intelligence. However, there is a recent trend to implement machine learning on end-point devices. These devices are located on the extreme edge, the border between the analog (physical world) and the digital world. They consist of one or more sensors and a resource-constrained embedded device, a device with a limited amount of memory, computing power, and power consumption.

The challenge is the development of accurate, energy-efficient machine learning models for deployment on these end-point devices.


Machine Learning at the Extreme Edge (ML@E2dge) looks at how a developer can apply machine learning in the development of accurate, energy-efficient, and intelligent (wireless) (battery-powered) end-point devices and systems. A machine learning model is developed, optimized, and deployed. We limit ourselves to a supervised machine learning regression problem. The project uses open-source software frameworks such as scikit-learn, TensorFlow, and Keras combined with Edge Impulse Studio. For experiment tracking, we use the MLOps tool Weights and Biases.
