The human body constantly generates a variety of signals that can be measured from the outside with wearable devices. These bio-signals — which include heart rate, sleep state and blood oxygen levels — can indicate whether someone is having mood swings or be used to diagnose a variety of bodily and brain disorders. It can be relatively cheap to gather a lot of bio-signal data. To teach a machine-learning algorithm to find a relationship between bio-signals and health outcomes, however, you need to teach the algorithm to recognize those health outcomes. https://lnkd.in/gu_at_hd
