Machine Learning @ the Extreme Edge

One of the challenges today is real-time and energy-efficient information extraction and processing at the edge by using Artificial Intelligence. However, there is a recent trend to implement machine learning on end-point devices. These end-point 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. Today's challenge is to develop accurate, energy-efficient machine learning models that can be deployed 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. Starting from a case study, a machine learning model is developed, optimized and deployed. In the project, we limit ourselves to a supervised machine learning regression problem. The selected end-point device is a Cortex®-M4 ARM® microcontroller (nRF52840, Nordic Semiconductor), in combination with an Inertial Measurement Unit (IMU) sensors (ex. XSens MTi-3 and Invensense ICM-20948). In the project open-source software frameworks such as scikit-learn, TensorFlow and Keras are used, in combination with Edge Impulse Studio. For experiment tracking, the MLOps tool Weights and Biases is used.
The outcome of the project is a guideline (a workflow) and (open source) software tools, that developers can use and apply in the design of the next generation of embedded intelligent end-point devices and systems.
