Abstract

Electroencephalogram (EEG) recordings often experience interference by different kinds of noise, including white and muscle, severely limiting its utility. Artificial neural networks (ANNs) are effective and powerful tools for removing interference from EEGs, but the quality of the separation is highly dependent on the type and degree of contamination. Several methods have been developed, but ANNs appear to be the most effective for reducing muscle contamination, especially when the contamination is greater in amplitude than the brain signal. We propose an ANN as a filter for EEG recordings, developing a novel framework for investigating and comparing the relative performance of an ANN incorporating real EEG recordings from the Clinical Neurophysiology Service at the Virgen de la Luz Hospital in Cuenca (Spain). This method was based on a growing ANN that optimised the number of nodes in the hidden layer and the coefficient matrices, which were optimised by the simultaneous perturbation method. The ANN improved the results obtained with the conventional EEG filtering techniques: wavelet, singular value decomposition, principal component analysis, adaptive filtering and independent components analysis. The system was evaluated within a wide range of EEG signals in which noise was added. The present study introduces a method of reducing all EEG interference signals with low EEG distortion and high noise reduction.
