Abstract
Methods, systems, and devices for sleep staging algorithms are described. A system may receive physiological data associated with a user from a wearable device, where the physiological data may be collected via the wearable device throughout a time interval. The system may identify a circadian rhythm adjustment model configured to weight the physiological data based on a circadian rhythm associated with the user. The system may input the physiological data and the circadian rhythm adjustment model into a machine learning classifier, and classify the physiological data, using the machine learning classifier, into at least one sleep stage of a set of sleep stages for at least a portion of the time interval, where the classifying is based on the circadian rhythm adjustment model. A graphical user interface (GUI) of a user device may display an indication of the at least one sleep stage based on classifying the physiological data.
