Abstract: Methods and systems, including computer programs encoded on a computer storage-medium, are disclosed for implementing intelligent detection of wellness events using mobile device sensors and cloud-based learning systems. A system obtains sensor data generated by sensors integrated in a mobile device of a user. A machine-learning (ML) engine of the system generates a predictive model that identifies behavioral trends of the user. The model is generated using a neural network trained to identify patterns representing user trends in the sensor data. Based on communications with the device, the model is used to generate activity profiles of the user from the behavioral trends. The model is used to detect abnormal events involving the user when a parameter value of the activity profile exceeds a threshold. Notifications directed to assisting the user with alleviating the abnormal event are generated after detecting the abnormal events.
