Background:

Altered mental status in critically ill patients requires objective assessment.
Electroencephalography (EEG) is a valuable tool for monitoring brain activity.
Automatic detection of vigilance states is essential for various applications.

Purpose of the Study:

To develop an automated method for determining vigilance and alertness states using EEG.
To apply EEG analysis for identifying fatigue driving.
To optimize a classification model for accurate alertness prediction.

Main Methods:

Utilized a discretization algorithm based on rough set theory for EEG feature selection.
Employed a Support Vector Machine (SVM) as the classification model for fatigue driving recognition.
Optimized SVM parameters using fatigue misjudgment risk control.

Main Results:

The rough set algorithm selected fewer features compared to principal component methods.
The method achieved accurate and fast prediction of alertness states in unseen individuals.
Feature selection varied across subjects, impacting SVM model establishment.

Conclusions:

The developed method provides an accurate and efficient way to predict alertness.
Rough set theory offers an effective approach for EEG feature selection.
The SVM model, optimized with risk control, demonstrates potential for real-world applications.
