13. A system (10), comprising:
- a sensor (20);
an input device(16);
an output device (18);
a processor (12);
computer-readable memory (14) including computer-readable instructions which, when executed by the processor (12), cause the processor (12) to perform the steps of;
acquiring (50) a signal indicative of power consumption;
detecting (52) a transient in the signal;
extracting (54) a feature indicative of the transient, wherein extracting the feature includes;
fitting (60) a plurality of models to the transient;
selecting (62) one of the plurality of models as a model for the transient;
defining (64) the feature indicative of the transient based on at least one parameter of the model for the transient; and
classifying (56) the transient based on the feature.
