1. A method of detecting deviation from an operational state of a rotational device, the method comprising:
receiving, from one or more sensor devices coupled to the rotational device, frequency domain data indicative of vibration data sensed during a sensing period;
processing the frequency domain data using a trained anomaly detection model to generate an anomaly score for the sensing period, wherein processing the frequency domain data comprises:
inputting the frequency domain data to an autoencoder; and
generating a residual based on an output of the autoencoder and the frequency domain data, wherein the anomaly score is based on the residual; and
processing the anomaly score using an alert generation model to determine whether to generate an alert.
