I saw the update. Would love to know how it differs and is improved from the previous algorithm. Thanks!
WHOOP’s sleep staging algorithm has been updated in a couple keys ways. First, WHOOP collected a lot more sleep data by partnering with sleep labs at Central Queensland University and University of Arizona. The increase in dataset size improves our machine learning model’s ability to learn the patterns in WHOOP sensor data that correspond to different stages of sleep. Second, WHOOP has developed new ways of interpreting sensor data collected by the WHOOP strap. These new interpretations give us new information about the member’s circadian rhythm and autonomic nervous system, which inform what stage of sleep the member is in.
