Self-optimizing neural network in the classification of real valued data

The classification of multi-dimensional patterns is one of the most popular and often most challenging problems of machine learning. That is why some new approaches are being tried, expected to improve existing ones. The article proposes a new technique based on the decision network called self-optimizing neural networks (SONN). The proposed approach works on discretized data. Using a special procedure, we assign a feature vector to each element of the real-valued dataset. Later the feature vectors are analyzed, and decision patterns are created using so-called discriminants. We focus on how these discriminants are used and influence the final classifier prediction. Moreover, we also discuss the influence of the neighborhood topology. In the article, we use three different datasets with different properties. All results obtained by derived methods are compared with those obtained with the well-known support vector machine (SVM) approach. The results prove that the proposed solutions give better results than SVM. We can see that the information obtained from a training set is better generalized, and the final accuracy of the classifier is higher.

Automated summary

This article introduces a self-optimizing neural network approach based on decision networks for the classification of multi-dimensional patterns. The approach utilizes feature vectors and discriminants to create decision patterns and discusses the influence of neighborhood topology. Experimental results demonstrate the superior performance of the proposed approach in terms of generalization and accuracy compared to the support vector machine method.
