1. A fault detection system for detecting faults in a turbine engine, the fault detection system comprising:

  • an encoding neural network, the encoding neural network receiving sensor data from the turbine engine, the encoding neural network creating plurality of scores from the sensor data, the plurality of scores comprising a reduced feature space representation of the sensor data; and

    a decoding neural network, the decoding neural network receiving the plurality of scores and creating a reconstructed estimate of the sensor data.
