Claim 19:
20. An apparatus for detecting deviation from an operational state of a rotational device, the apparatus comprising:
means for receiving, from one or more sensor devices coupled to the rotational device, frequency domain data indicative of vibration data sensed during a sensing period;
means for generating an anomaly score for the sensing period based on the frequency domain data, wherein the means for generating the anomaly score includes:
means for generating a reconstruction of the frequency domain data; and
means for generating a residual based on a difference between the frequency domain data and the reconstruction of the frequency domain data, wherein the anomaly score is based on the residual; and

means for determining, based on the anomaly score, whether to generate an alert.
