    Neural networks (NN), with their parallel processing power, can be used as a tool to forecast stock exchange events (SEE), as a sub-domain of time-series (TS) forecasting. For the final product of SEE forecasts, other external economical factors have to be taken also into consideration and to be combined with the pure TS forecast. In this paper we present the energy function construction and imple... View full abstract»

    Backpropagation (BP) method with momentum has often been applied to adapt artificial neural networks for various pattern classification problems. However, an important limitation of this method is that its learning performance depends heavily upon the selection of the values of momentum factor and step size. In this paper, it is shown that the hierarchical structure stochastic automata can be used... View full abstract»

    This paper describes a method of utilising genetic algorithms to train fixed architecture feedforward and recurrent neural networks. The technique described uses the genetic algorithm to evolve changes to the weights and biases of the network rather than the weights and biases themselves. Results achieved by this technique indicate that for many problems it compares very favourably with the more c... View full abstract»

    The recombination operator plays a very important role in genetic algorithms. We present binary coded genetic algorithms in which more than two parents are involved in the recombination operation. We propose two types of multi-parent recombination operators, the multi-cut (MX) and seed crossover (SX). Each of these operators is a natural generalization of two parents recombination operator. These ... View full abstract»

    We have proposed a two-level architecture for brain computing, where two levels are introduced for processing of meta-symbol. At Level 1 a conventional pattern recognition is performed, where neural computation is included, and its output gives the meta-symbol which is a symbol enlarged from a symbol to a kind of pattern. At Level 2 an algorithm acquisition is made by using a state machine for abs... View full abstract»
