- Abstract
In this paper, a novel focused time lagged recurrent neural network (FTLR NN) with gamma memory filter is designed
to learn the subtle complex dynamics of a typical magnetic stirrer process. Magnetic stirrer exhibits complex nonlinear
operations where reaction is exothermic. It appears to us that identification of such a highly nonlinear system is not yet
reported by other researchers using neural networks. As magnetic stirrer process includes time relationship in the
input-output mappings, time lagged recurrent neural network is particularly used for identification purpose. The
standard back propagation algorithm with momentum term has been proposed in this model. The various parameters
like number of processing elements, number of hidden layers, training and testing percentage, learning rule and
transfer function in hidden and output layer are investigated on the basis of performance measures like MSE, NMSE
and correlation coefficient on testing data set. Finally, effect of different norms are tested along with variation in gamma
memory filter. It is shown that dynamic NN model has a remarkable system identification capability for the problem
considered in this paper. Thus, FTLR NN with gamma memory filter can be used to learn underlying highly nonlinear
dynamics of the system, which is major contribution of this paper.
