In this tutorial, we’ll demonstrate how to use the Sony Spresense plus the SensiEDGE CommonSense add-on board to build and deploy sensor fusion-based machine learning models. We’ll go through this process under the premise of a product development workflow, from prototype to production. We’ll cover data collection, algorithm creation, testing, and deployment to the Spresense. Finally, we’ll discuss what it takes to scale the solution to a physical product.
