Abstract
In the field of intelligent design, much attention is paid to the generation of design knowledge and experience. Today, EEG signal is a direct method to explore the design idea and brain consciousness. The purpose of this paper is to establish a basic geometric representation pattern of EEG signals. Firstly, the basic geometry representation of EEG signal is given, EEG signal is collected and the preprocessing method of EEG signal is proposed. Then, the feature extraction and recognition method of EEG signal is described, and the recognition rate is improved by feature decision fusion. Finally, the correctness of the representation pattern is verified by experiments.
