A New Feature Analysis Approach to Selecting Channels of EEG for Fatigue Driving

Algorithm 2

SFS.

Input: Feature set of dimension , where is the number of samples, is the number of features; characteristic function ;

Output: Optimal feature set of dimension , where is the selected number of features;

1: Set the empty set ;

2: For each feature in feature set :

   Select from and join the . Calcualte the via a classifier based on the ;

3: When reaches optimal, output the optimal feature set .
