WebAug 13, 2024 · Heart rate was derived from pulse oximetry, which uses PPG, increasing the comparability of the Apple Watch (training) and MESA (testing) set. The “clock proxy” feature was derived from the ambulatory actigraphy recording for each MESA participant. Results Demographic and summary PSG data WebThe E4 was used to collect sleep data and, altogether, 110 features were extracted from each night’s biosignals, and used to train machine learning models. The experiments showed that early symptoms for migraine are highly personal, and that using personal recognition models the accuracy for detecting attacks one night prior is over 84%.
