Abstract

Electro encephalog ram(EEG) can reflect the thinking activity of the brain under different conditions, therefore, motor imagery recognition based on EEG has become a new research hot spot. To reduce the influence of low-quality samples on the session-to-session transfer performance of CSP filter models and improve the recognition accuracy ratio, this paper proposed an incremental updating algorithm for CSP filter based on training sample evaluation. It used sample selection method to evaluate the quality of EEG data. Then it removed a set of training data corresponding to low recognition rate. Finally, it updated the CSP filter incrementally which designed by the optimized sample. In label environment, the motor imagery recognition of EEG signals reaches average accuracy of 80.92%. Compared with the traditional CSP method, the average recognition rate of the five subjects' testing sets increases by 5.4%, 5.6%, 1.5%, 8.6%, and 7.7%, respectively. The experimental results verify the effectiveness of the proposed algorithm.
