A major problem of neural network in real-time
applications is their long training time. We present a
modification of the neural network (NN) for reduction of training time. Unlike traditional training time reduction
algorithms, we propose a new Adaptive Fuzzy technique to create ensembles of neural network using multiple projections of the same data obtained from different NNs. The purpose of this paper is to demonstrate the optimization of training that occurs with the application of fuzzy controller theory to neural network.
A fuzzy system is employed to control the learning parameters of a neural network to reduce the possibility of overshooting during the learning process. Hence, the learning time can be shortened. This paper compares the training efficiency and accuracy between a NN and a fuzzy controlled neural network, when they are required to carry out the same assignment. We justify the suitability of the proposed method by some experiments in soccer robot trajectory generation tasks; the resulting fuzzy controlled neural network indicates a significant reduction in the training time by 30%
