Abstract
The study presents drowsiness classification by analyzing the Electroencephalograph (EEG) signals. The EEG signals of different drowsiness situations such as active, drowsy and sleep are captured from many individuals using a multichannel electrode system. We consider the dominant electrode pair FPZ-CZ and PZ-OZ in this study. Denoising of the signal is done for clarity and band pass filtering is done with the required cutoff frequency. In order to get the five sub bands (delta, theta, alpha, beta and gamma) of EEG signal, third order Daubechies wavelet transform is used to decompose. Statistical analysis and energy features are calculated of these sub bands for the effective classification. Classification is done in two stages which starts from clustering of the feature data using K-means and later effective classification using the Support Vector Machine (SVM) which uses the Gaussian kernel. Work has been carried out in the famous Physiobank Sleep Database. Result is very promising and it overcomes many limitations by using the unsupervised learning and the effective classification.
