This work is an implementation of filter-bank common spatial pattern (FBCSP)[1] on BCI Competition IV dataset 2a. While the dataset consist of four class, this work will only use two class which are left and right hand
Early result on train and test data, SVM model is used as classifier, 5-fold CV is used to evaluate model performance
