==Introduction==Classification of materials is another interesting use case where Machine Learning (ML for short) opens the doors for promising developments related to smart edge devices. In this Technical Note (TN), different implementations of ML-based material classification applications are compared in terms of performance and development workflow. Tests were run on embedded platforms such devices may be built uponThe classification process makes use of spectroscopy: the model consists of a neural network (NN) fed with measurement data produced by a spectrometer.
