Abstract: Disease prediction using analyte measurements and machine learning is described. In one or more implementations, a combination of features of analyte measurements may be selected from a plurality of features of the analyte measurements based on a robustness metric and a performance metric of the combination, and a machine learning model may be trained to predict a health condition classification using the combination. The performance metric may be associated with an accuracy of predicting the health condition classification, and the robustness metric may be associated with an insensitivity to analyte sensor manufacturing variabilities on the accuracy. Once trained, the machine learning model predicts the health condition classification for a user based on analyte measurements of the user collected by a wearable analyte monitoring device. The combination of features may be extracted from the analyte measurements of the user and input into the machine learning model to predict the classification.

Abstract: A cardiovascular detection system and method, comprising an active compression cuff contracting at a frequency higher than the systolic frequency of the heart. Meanwhile, the detection device is used to capture the influence of the active compression cuff and cardiac systole on the blood of the part to be detected. In addition, it is supplemented by electrocardiography to monitor the reference value of cardiac systole to distinguish the difference between the pulse wave generated by the active compression cuff and the pulse wave generated by the heart. In this way, the state of the cardiovascular system can be quickly understood. Since the active compression cuff is contracted at a frequency higher than the systolic frequency of the heart, it can be more accurately determined whether the blood vessel is blocked or hardened.
