Abstract

Using the method of brain network graph to analyze EEG functional connectivity has the problems of threshold selection and ignoring brain dynamic. To solve this problem, This paper proposed a method of using topological dynamic mode-ling to analyze the EEG functional connectivity matrix, which improved the accuracy of classification and recognition of mental arithmetic tasks. Firstly, it mapped the functional connectivity matrix to an undirected weighted graph. Then it used the persistent Homology Toolbox to construct different complexes and record the different levels of homology features formed in this topological dynamic process to form the persistence diagrams. Finally, it calculated the persistence landscape features as the input feature of the random forest classifier for mental state recognition. In the two task of mental arithmetic state recognition and mental arithmetic quality classification, the proposed algorithm obtained the highest recognition accuracy at 99.26% and 99.20%, sensitivity at 97.87% and 99.80% and specificity at 99.78% and 97.64%, respectively, and accuracy at 66.81% and 66.85% in the cross-individual verification experiment. Experimental results show that the proposed algorithm is fully considered all possible thresholds and effectively extracts the classification information of EEG functional connectivity to implement the automatic recognition of EEG mental arithmetic state.
