Using the Edge Impulse infrastructure to source and process data made it easier for Oura to obtain high-quality data for their ML training. Having sifted through all the available data in a matter of weeks, instead of months or years, Oura was able to narrow their focus and extract only three types of sensor data. The new dataset, covering heart rate, motion, and body temperature, produced higher correlation accuracy across the board. In the most challenging case, correlation accuracy increased by 17 points, from 62% to 79%. This is the best result that any wearable manufacturer has posted to date.
Now that the Edge Impulse infrastructure is in place, Oura can begin new projects and acquire new types of data, to support different areas of wellness. The revised application uses a subset of features, but the complete dataset, with its full complement of identified features, remains accessible and usable, so Oura can add features to their algorithm whenever they want or experiment with new capabilities. The Edge Impulse infrastructure can also be expanded, to take advantage of additional functionality. For example, the pre-processing pipeline can be configured to automatically feed into a project, so the project can automatically be retained and then score all data. Oura is already exploring this concept for use with activity detection, and has more than a dozen Edge Impulse projects active in this area.
Edge Impulse Rolls Out Support for BrainChip's Neuromorphic Akida Edge AI Platform
Inspired by the operation of the human brain Akida promises better performance at a lower power draw — and is now supported in Edge Impulse.www.hackster.io
Bit of Akida magic will take Oura products to a whole new level !
Oura should be one of the first customers of the rank.

Director of Strategic Partnerships & Global IoT, Renesas
"The sleep data we collect is... messy and hard to scrub. Edge Impulse makes it easy to bring data in, combine it, and refine it, so we can get as much value out of it as possible."
