Abstract: In one embodiment a method for providing presence information in a smart environment is implemented on a personal computing device associated with a user and includes: broadcasting a presence indicator signal in the smart environment, where the presence indicator signal indicates presence of the user in the smart environment, and the personal computing device is not provided by an operator of the smart environment.

Abstract: In one embodiment, an issue analysis service obtains telemetry data from a plurality of devices in a network across a plurality of time intervals. The service detects a failure event in which a device in the network is in a failure state. The service clusters the telemetry data obtained prior to the failure event into rounds according to time intervals in which the telemetry data was collected. Each round corresponds to a particular time interval. The service applies a machine learning-based classifier to each one of the rounds of clustered telemetry data to identify one or more common traits appearing in the telemetry data for each round. The service generates a trait change report indicating a change in the one or more common traits appearing in the telemetry data across the rounds leading up to the failure event.
