The objective of this study is to improve the accuracy of classification for a multi-imagery task by using canonical variates analysis in a brain-computer interface (BCI). Electroencephalogram (EEG) is recorded from subjects performing a four-class motor imaginary task, left hand, right hand, foot and tongue. Temporal features are extracted as squared band pass filtered EEG, and frequency features...
To Solve the problem of low accuracy and high false alarm, a construction method of Bagging ensemble based on random subspace PCA (Principle Component Analysis) was proposed. To create a training data for a base classifier, the feature set is randomly split into several subsets and PCA is applied to each subset. all principal components are retained to keep the variety information in the data; To...
In this paper, an experiment was designed to get the electroencephalography (EEG) when people caught the vision of moving to different direction (right, left, front, back). Through Fourier Transform., the feature of the EEG was obtained. Then, the algorithm of principal component analysis (PCA) was used to simplify the feature. Finally, in order to classify the direction perception EEG, it was distinguished...
