چکیده

This paper proposes an artificial neural network RBF to classification using feature descriptors. The theoretical and practical aspects of theory F distributions with different degrees of freedom introduced. The distribution F densities are similar in shape, making it difficult to identify the differences between the two densities. This paper is concerned with separating these same probability densities with different degrees of freedom using feature descriptors, identified by pruning a Radial Basis Function (RBF) network using pivoted QLP decomposition generated for densities function, and its validity were evaluated by the rate of correct classification. The QLP method proves efficient for reducing the network size by pruning hidden nodes, resulting is a parsimonious model which identifies four main features (namely kurtosis and skewness and mean). The classification model induced by the methodology show, in general, good results. Key-Words: Radial Basis Function, Pivoted QLP Decomposition, Pruning, F distribution

Analysis of the characteristic features of the density functions for gamma, Weibull and log-normal distributions through RBF network pruning with QLP

The Weibull, Gamma and Log-normal densities are similar in shape for the same coefficient of variation, making it difficult to identify the differences between the three densities. This paper is concerned with separating these three probability densities using feature descriptors, identified by pruning a Radial Basis Function (RBF) network using pivoted QLP decomposition generated for each dens...

Regression with Radial Basis Function artificial neural networks using QLP decomposition to prune hidden nodes with different functional form

Radial Basis Function networks with linear output are often used in regression problems because they can be substantially faster to train than Multi-layer Perceptrons. We show how radial base Cauchy, multiquadric and Inverse multiquadric type functions can be used to approximate a rapidly changing continuous test function. In this paper, the performance of the reduced matrix design by QLP decom...
