Comparative Analisys of Different Approaches Towards Multilayer Percentron Training

A comparative analysis of four multilayer perceptron learning algorithms is exposed in this work: the error backpropagation algorithm and three other algorithms with fundamentally different approaches towards the improvement of convergence time. Stock exchange share price prediction is at the basis of the comparison of the algorithms. The optimal neural network topology for the solution of the above-mentioned task is determined in this work. Furthermore the forecasts concerning four neural networks with the same topology, but trained with the help of different algorithms are being compared. Special attention is paid to the generalisation ability of neural networks. A series of reasons, which can cause neural network forecast delay problems, is mentioned
