T. Miyano et al., PREDICTING CHAOTIC SEQUENCES IN A BLAST-FURNACE BY A GENERALIZED RADIAL BASIS FUNCTION NETWORK, Electronics and communications in Japan. Part 3, Fundamental electronic science, 79(7), 1996, pp. 1-10
Nonlinear forecasting is applied to characterize the complexities in t
ime series of temperature fluctuations and pressure fluctuations obser
ved in a blast furnace. A generalized radial basis function network an
d a Sugihara-May predictor are used as the predictive models. The temp
erature sequence may be diagnosed as low-dimensional chaos according t
o the scaling property of the prediction error as a function of the pr
ediction-time interval. Short-term forecasts about the temperature seq
uence are successfully made by the network that has learned the underl
ying dynamics embedded in three-dimensional delayed space.
