1. A system for determining a most probable cause or causes of a problem for a plant, said system comprising:

  • a plant, said plant having a plurality of subsystems that contribute to the operation of the plant, said plurality of subsystems having operating functions that produce operational signals;

    a plurality of sensors operable to detect said operational signals from said plurality of subsystems and transmit data related to said operational signals;

    an advisory system operable to receive an input, said input selected from the group consisting of data from said plurality of sensors, possible input causes of the problem, possible input symptoms of the problem and combinations thereof;

    said advisory system also having an autoencoder in the form of a recurrent neural network (RNN), said RNN having sparse connectivity and a plurality of nodes, said autoencoder also operable to receive said input and perform multiple iterations of computations at each of said plurality of nodes as a function of said input and provide an output;

    said output selected from the group consisting of possible output causes of the problem, possible output symptoms of the problem and combinations thereof.
