Claim 9:
10. A system to detect deviation from an operational state of a vibrating device, the system comprising:
a memory including a trained anomaly detection model and an alert generation model; and
one or more processors coupled to the memory, the one or more processors configured to:
process, using the trained anomaly detection model, frequency domain data indicative of vibration data sensed during a sensing period, the trained anomaly detection model configured 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

process the anomaly score using an alert generation model to determine whether to generate an alert.
