Data Set Information:

IMPORTANT: we have lower performance on 'leave-one-subject-out' tests. The performance baseline index we established is for 10-fold cross-validation tests. Therefore, there's much more space for optimization in subject independent tests. If you need more information, please send us an e-mail.
