1. A method of balancing a rotating system of an engine, the method comprising:
receiving, by one or more processors, data that includes parameter values for parameters associated with the rotating system;
generating, by the one or more processors, a transfer function specific to the rotating system by applying a machine-learned model to the parameter values including generating, by the one or more processors, a main effects plot for respective ones of the parameters associated with the rotating system by applying the machine-learned model to the parameter values for the parameters associated with the rotating system;
generating, by the one or more processors, a balance shot as an output of the machine-learned model based at least in part on the transfer function specific to the rotating system, the balance shot indicating one or more physical locations at which one or more balancing weights are to be added or removed from the rotating system; and
attaching to or removing from the rotating system the one or more balancing weights based at least in part on the balance shot.
