A structure composed of local linear perceptrons for approximating global class discriminants is investigated. Such local linear models may be combined in a cooperative or competitive way. In the cooperative model, a weighted sum of the outputs of the local perceptrons is computed where the weight is a function of the distance between the input and the position of the local perceptron. In the c...

In this paper, a comparison study is presented on artificial intelligence and time series models in 1-hour-ahead wind speed forecasting. Three types of typical neural networks, namely adaptive linear element, multilayer perceptrons, and radial basis function, and ARMA time series model are investigated. The wind speed data used are the hourly mean wind speed data collected at Binalood site in I...

Neural networks are organized in committees to improve the correctness of the decisions created by artificial neural networks (ANN’s). In the classification of human chromosomes, it is accustomed to use multilayer perceptrons with multiple (22-24) outputs. Because of the huge number of synaptic weights to be tuned, these classifiers cannot go beyond a level of 92% overall correctness. In this s...

This paper presents a method for massively parallel learning of part-of-speech disambiguation based on a minmax modular neural network model. The method has three main steps. Firstly, a large-scale tagging problem is decomposed into a number of relatively smaller and simpler subproblems according to the class relations among a given training corpus. Secondly, all of the subproblems are learned ...
