چکیده

In this study we introduce a neural network ensemble composed of several linear perceptrons, to be used as a classifier that can rapidly be trained and effectively deals with nonlinear problems. Although each member of the ensemble can only deal with linear classification problems, through a competitive training mechanism, the ensemble is able to automatically allocate a part of the learning space that is linearly separable to each member, thus decomposing non-linear classification problems into several more manageable linear problems. Each member is equipped with an additional output neuron that produces a “confidence” value indicating the reliability of that member with regard to a given input. In the classification task, the confidence values of the ensemble’s members are used to decide a final output for the ensemble. We believe that the ability of the ensemble can improve the performance of general classifiers. Keywords—Neural Network Ensemble, Linear Perceptrons, Competitive Learning

Multi-Layer Perceptrons as Nonlinear Generative Models for Unsupervised Learning: a Bayesian Treatment

In this paper, multi-layer perceptrons are used as nonlinear generative models. The problem of indeterminacy of the models is resolved using a recently developed Bayesian method called ensemble learning. Using a Bayesian approach, models can be compared according to their probabilities. In simulations with artiicial data, the network is able to nd the underlying causes of the observations despi...

Ensemble learning of linear perceptrons; Online learning theory

Abstract Within the framework of on-line learning, we study the generalization error of an ensemble learning machine learning from a linear teacher perceptron. The generalization error achieved by an ensemble of linear perceptrons having homogeneous or inhomogeneous initial weight vectors is precisely calculated at the thermodynamic limit of a large number of input elements and shows rich behav...

Increasing the accuracy of the classification of diabetic patients in terms of functional limitation using linear and nonlinear combinations of biomarkers: Ramp AUC method

The Area under the ROC Curve (AUC) is a common index for evaluating the ability of the biomarkers for classification. In practice, a single biomarker has limited classification ability, so to improve the classification performance, we are interested in combining biomarkers linearly and nonlinearly. In this study, while introducing various types of loss functions, the Ramp AUC method and some of...

Optimum Ensemble Classification for Fully Polarimetric SAR Data Using Global-Local Classification Approach

In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
