Abstract
A method includes obtaining sensor data associated with operation of one or more devices and providing input data based on the sensor data to a dimensional-reduction model having an encoder portion and a decoder portion and configured such that the encoder portion is not mirrored by the decoder portion. The method also includes obtaining output data from the dimensional-reduction model responsive to the input data and determining a reconstruction error indicating a difference between the input data and the output data. The method also includes performing a comparison of the reconstruction error to an anomaly detection criterion and generating an anomaly detection output for the one or more devices based on a result of the comparison.
