A new feature fusion based technique for classifying multi-
class motor imagery problems
Author(s): Jack Ma*
The benefit of a Motor Imagery-Based Brain Computer Interface (MI-BCI) is its great independence, which may rely on the user's spontaneous brain activity to run external equipment. However, MI-BCI still suffers from a lack of control effect, which necessitates the use of more efficient feature extraction techniques and classification approaches to extract distinctively separable features from Electroencephalogram (EEG) data. This study suggests a new framework based on bispectrum, entropy, and a similar spatial pattern. We extract MI-EEG signal characteristics using three methods: bispectrum in higher order spectra, entropy, and CSP, and then pick the most contributing features using a tree-based feature selection algorithm. SVM, Random Forest, Naive Bayes, LDA, KNN, Xgboost, and Adaboost classification results were compared, finally, we decided to employ the SVM technique based o.. Read More»
