Abstract:
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 being only data from said plurality of sensors and a partial list of possible input causes of the problem or only a partial list of possible input symptoms of the problem; 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.
