摘要
The time consuming training of dynamic neural networks often prohobits the industrial application. This paper presents a fast method to train neural networks with external dynamics for nonlinear dynamic system identification. The proposed method selects first a suitable set of neurons and trains the resulting network in a second step. This proposed procedure leads to faster convergence compared to standard training algorithms and comparable accuracy.
