Abstract
Systems, methods, and other embodiments described herein relate to predicting anomalous operation of a device and an associated remaining useful life (RUL). In one embodiment, a method includes acquiring usage information about operation of an electronic device. The method includes selecting at least one feature from the usage information according to an optimization. The method includes determining whether the least one feature indicates a presence of an anomaly in the operation of the electronic device according to an anomaly model. The method includes, responsive to detecting the anomaly, determining a remaining useful life (RUL) for the electronic device according to a RUL model. The method includes providing the RUL.
