| spelling | oai:repository.up.ac.za:2263/28618 Using particle swarm optimisation to train feedforward neural networks in dynamic environments Engelbrecht, Andries P. myearwen@gmail.com Rakitianskaia, A.S. (Anastassia Sergeevna) Computational intelligence Particle swarm optimization (PSO) Concept drift Neural networks UCTD Dissertation (MSc)--University of Pretoria, 2011. The feedforward neural network (NN) is a mathematical model capable of representing any non-linear relationship between input and output data. It has been succesfully applied to a wide variety of classification and function approximation problems. Various neural network training algorithms were developed, including the particle swarm optimiser (PSO), which was shown to outperform the standard back propagation training algorithm on a selection of problems. However, it was usually assumed that the environment in which a NN operates is static. Such an assumption is often not valid for real life problems, and the training algorithms have to be adapted accordingly. Various dynamic versions of the PSO have already been developed. This work investigates the applicability of dynamic PSO algorithms to NN training in dynamic environments, and compares the performance of dynamic PSO algorithms to the performance of back propagation. Three popular dynamic PSO variants are considered. The extent of adaptive properties of back propagation and dynamic PSO under different kinds of dynamic environments is determined. Dynamic PSO is shown to be a viable alternative to back propagation, especially under the environments exhibiting infrequent gradual changes. Copyright 2011, University of Pretoria.
