Study on Bayes Discriminant Analysis of EEG Data

The Open Biomedical Engineering Journal 31 December 2014 RESEARCH ARTICLE DOI: 10.2174/1874120701408010142

Abstract

Objective:

In this paper, we have done Bayes Discriminant analysis to EEG data of experiment objects which are recorded impersonally come up with a relatively accurate method used in feature extraction and classification decisions.

Methods:

In accordance with the strength of α wave, the head electrodes are divided into four species. In use of part of 21 electrodes EEG data of 63 people, we have done Bayes Discriminant analysis to EEG data of six objects. Results in use of part of EEG data of 63 people, we have done Bayes Discriminant analysis, the electrode classification accuracy rates is 64.4%.

Conclusions:

Bayes Discriminant has higher prediction accuracy, EEG features (mainly α wave) extract more accurate. Bayes Discriminant would be better applied to the feature extraction and classification decisions of EEG data.

Keywords: Electroencephalogram, Bayes Discriminant, α rhythm, electrode classification, feature extraction.
