Hy. Yu et Sy. Bang, AN IMPROVED TIME-SERIES PREDICTION BY APPLYING THE LAYER-BY-LAYER LEARNING-METHOD TO FIR NEURAL NETWORKS, Neural networks, 10(9), 1997, pp. 1717-1729
The FIR neural network model was recently proposed for time series pre
diction and gave good results. However the learning algorithm used for
the FIR network is a kind of gradient descent method and hence inheri
ts all the well-known problems of the method. Recently a new learning
algorithm called the optimization layer by layer was proposed for the
regular multilayer perceptron network, and showed a great improvement
in the learning time as well as the performance of the network. In thi
s paper we develop a new learning algorithm for the FIR neural network
model by applying the idea of the optimization layer by layer to the
model. The results of the experiment, using two popular time series pr
ediction problems, show that the new algorithm is far better in learni
ng rime and more accurate in prediction performance than the original
learning algorithm. (C) 1997 Elsevier Science Ltd. All rights reserved
