✦ Synopsis
The FIR neural network model was recently proposed for time series prediction and gave good results. However, the learning algorithm used for the FIR network is a kind of gradient descent method and hence inherits 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 this 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 prediction problems, show that the new algorithm is far better in learning time and more accurate in prediction performance than the original learning algorithm.
