Since that electroencephalogram (EEG) signals
contains vital information about brain health for better
diagnosis analyzing EEG signals is important.

This paper
developed new classifier architecture using combined neural
network (NN)-wavelet transformer (WT) and statistical methods
to classification EEG signals. For increasing the accuracy and
speed of classification, the exact classes are determined using
WARD multivariate statistical methods and dendogram graph.
Then discrete WT (DWT) and wavelet packet (WP) coefficients
of EEG signals are applied to training of NN separately. For
determining the effect of NN training method in results two
different supervised and unsupervised NN is selected: multilayer
perceptron (MLP) and learning vector quantization (LVQ).
Classification accuracy of LVQ-WT, LVQ-WP and MLP-WT
methods is 95.67%, 97% and 98.67% respectively that show good
ability ofMLP-WT in classification.
