Features of building a predictive neuro-fuzzy network

The article discusses the features of building a predictive neuro-fuzzy network. During the research, the structure of an adaptive neuro-fuzzy predictor and a multidimensional neuro-fuzzy neuron is presented. The principle of processing information received in real time about the operation of a piston engine of a SEP using a TSK-system of zero order with the use of high-speed optimization procedures of the second order such as the recurrent least squares method for adjusting synaptic weights is considered. The architecture of an artificial neuro-fuzzy network for predicting the resource strength of a piston engine SEU brand RND 105, consisting of five layers connected in series, has been determined. The structure of dynamic filter neurons with finite impulse response is presented. The procedure for training a neural network is considered. During the numerical experiment, the following evaluation criteria were used: MSE (mean squared error); SMAPE (Symmetric mean absolute percentage error) - characterizes the forecast error in percentage. An experimental analysis of the developed network was carried out on the example of predicting the resource strength of an eight-cylinder two-stroke marine diesel engine of the RND 105 brand.
