Claim 18:
19. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
train a machine learning (ML) model to infer one of a plurality of electronic control unit (ECU) labels based on a plurality of voltage signatures, each voltage signature comprising one of a plurality of message identifications (MIDs) of messages transmitted on a bus;
determine whether two or more MIDs of the plurality of MIDs overlap based on an overlap threshold, the overlap threshold to comprise a percentage value that represents an amount of time that at least one of the two or more MIDs is misclassified by the ML model;
collapse the two or more MIDs of the plurality of MIDs into a one of the plurality of ECU labels to generate an updated mapping between MIDs and ECU labels responsive to a determination that the two or more MIDs of the plurality of MIDs overlap; and
train the ML model on the updated mapping between the plurality of voltage signatures and the plurality of ECU labels.
