Reducing noise impact on MLP training

Abstract

In this paper we propose and discuss several new approaches to noise-resistant training of multilayer perceptron neural networks. Two groups of approaches: input ones, based on instance selection and outlier detection, and output ones, based on modified robust error objective functions, are presented and compared. In addition we compare them to some known methods. The experimental evaluation of the methods on classification and regression tasks and comparison of their performances for different amounts of noise in the training data, proves the effectiveness of the proposed approaches.
