Please predict whether this patent is acceptable.PATENT ABSTRACT: Electrical usage of devices in a building may be monitored to assist a user in labeling devices. In some implementations, a user may provide information about a first device, and this information may be used to obtain a plurality of mathematical models that each correspond to a device or a class of devices. The mathematical models may be used to process an electrical signal, and a score may be generated for each mathematical model. A mathematical model may be selected from the plurality of mathematical models using the scores, such as selecting a mathematical model with a highest score. The first device may be associated with the selected mathematical model.
