Tw. Karjala et Dm. Himmelblau, DYNAMIC DATA RECTIFICATION BY RECURRENT NEURAL NETWORKS VS TRADITIONAL METHODS, AIChE journal, 40(11), 1994, pp. 1865-1875
Recurrent neural networks are used to demonstrate the dynamic data rec
tification of process measurements containing Gaussian noise. The perf
ormance of these networks is compared to the traditional extended Kalm
an filtering approach and to published results for model-based nonline
ar programming techniques for data reconciliation. The recurrent netwo
rk architecture is shown to provide comparable, if not superior, resul
ts when compared to traditional methods. The networks used were traine
d using conventional nonlinear programming techniques in a batch fashi
on.
