CSP-Ph-PS: Learning CSP-phase space and Poincare sections based on evolutionary algorithm for EEG signals recognition

作者:

Highlights:

• We proposed a new feature extraction method.

• Features are extracted based on optimal Poincare sections that fitted on phase space.

• Optimal phase space reconstructed based on filtered data using CSP.

• BCI Competition III and BCI Competition IV datasets is utilized to evaluation.

• Presented model reached the accuracy of 89.76% and 71.87% for datasets, respectively.
